Saanch — FAQ

Yes, Saanch is free to use, available now on Android via Google Play, with iOS coming soon. We believe ambient soundscapes that help with sleep are a utility — something people should have access to, not a feature locked behind a paywall.

You'll need to sign in with Google to set up Saanch — account creation isn't optional. Once you're signed in, though, your alarms, to-do lists, notes, and cached soundscapes are stored locally on your device, so day-to-day use doesn't require a constant internet connection.

Yes. Signing in with Google is required to set up and use Saanch — there's currently no guest mode or account-free option. This is what lets your alarms, soundscapes, and to-do lists sync reliably and keeps your data tied to a single, secure account.

Yes. Saanch uses Android's exact alarm scheduling so your alarm fires at the precise time you set, even if the system tries to delay it during deep sleep (Doze) mode. It also automatically re-registers all your alarms if your phone restarts, so a reboot or battery drain won't silently cancel them.

Saanch combines ambient soundscapes and focus audio environments, contextual task management, and a high-precision alarm system in one app — built for people who want reliable sleep, focus, and wake-up tools without juggling three separate apps.

Yes. All data sent between the app and our servers is encrypted in transit (TLS/HTTPS). Since signing in with Google is required to use Saanch, we only collect your email, name, and profile picture to identify your account — we never see or store your Google password, and we never sell your personal identifiers to advertisers.

Each permission exists to make the alarm and audio features actually reliable: waking your screen from a locked, sleeping phone, keeping soundscapes playing uninterrupted in the background, and displaying a full-screen alarm even over other apps. Without them, Android would be free to delay or silently kill the alarm.

Saanch is currently available for Android on Google Play. An iOS version is coming soon.

Most apps do one thing — either alarms, or ambient sound, or a to-do list. Saanch is built around all three working together, with alarm reliability (exact scheduling, boot recovery, full-screen wake) treated as a core engineering priority rather than an afterthought.

Saanch is a sleep, focus, and productivity app that combines ambient soundscapes, focus audio environments, contextual to-do lists, and a high-precision alarm system in one place. It's built for people who want dependable tools for falling asleep, staying focused, and waking up — without stitching together three or four separate apps.

Saanch is for anyone who struggles to fall asleep in a fully silent room, needs steady background sound to concentrate, or has been let down by an alarm app that didn't fire reliably. That includes light sleepers, people working from noisy or distracting environments, students, and anyone who has found ambient sound genuinely helpful for attention difficulties.

Yes. Saanch's ambient soundscapes are designed to mask sudden noises and create a consistent, calming environment for falling asleep, and its alarm system is built to wake you gently and reliably in the morning — so both ends of the night are covered in one app.

Yes. The same soundscape engine that supports sleep also powers focus audio environments — steady, non-distracting sound designed to help you settle into study or deep work — paired with contextual to-do lists so your focus tools and your task list live in one place.

Saanch is built around ambient soundscapes rather than music with lyrics, since research on the "irrelevant speech effect" suggests lyrics can compete for the same mental resources you need for reading, writing, or sleep. You're welcome to run Saanch alongside a separate music app if you prefer, but its soundscapes are designed to work well entirely on their own.

Yes, though for overnight use, sleep specialists generally recommend a speaker placed a few feet away rather than headphones or earbuds, to avoid sustained volume close to your ears for hours at a time. For daytime focus sessions, headphones work well since you're awake and can adjust volume as needed.

Yes. Saanch is designed to keep soundscapes playing uninterrupted in the background while you use other apps — part of why it asks for the permissions it does, since without them Android is free to pause or kill background audio.

Yes. You can set a timer when you start a soundscape, and playback stops automatically once the timer hits — so you're not stuck choosing between a soundscape running all night or manually turning it off. It's a simple way to get the benefits of ambient sound for falling asleep without it playing for hours after you've already drifted off.

Yes. Saanch is built to display a full-screen alarm and wake your screen even when your phone is locked and asleep, using the same permissions that keep it reliable through Android's Doze mode.

Not yet. Saanch is currently built around ambient soundscapes and focus environments rather than narrated sleep stories, but it's a feature we're planning to add — for now, soundscapes are the core sleep tool.

Meditation apps like Calm and Headspace are generally built around guided sessions — meditations, sleep stories, breathing exercises. Saanch takes a different angle: it's built around passive ambient soundscapes plus a genuinely reliable alarm and lightweight task management, for people who want dependable background sound and a wake-up system rather than a guided-session library.

Neither — it's built to do both equally, using the same underlying soundscape engine. Some people open Saanch only at night, others only during work hours, and many use it for both, since the sound principles that help you fall asleep (steady, non-intrusive, no lyrics) largely overlap with what helps you concentrate.

Insomnia is a common sleep disorder involving trouble falling asleep, staying asleep, or waking up too early and being unable to get back to sleep. Occasional insomnia is often linked to stress, screen time, or an irregular schedule — but if it persists for weeks and starts affecting daily life, it's worth discussing with a doctor.

Yes, for many people. Steady background sound — like rain, white noise, or ambient soundscapes — can mask sudden noises that interrupt sleep and create a consistent, calming environment that makes it easier to fall asleep. It's not a cure for chronic insomnia, but it's a widely used, low-effort part of good sleep hygiene alongside a consistent bedtime and a dark, cool room.

ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects a person's ability to sustain attention, regulate impulses, and manage energy levels. It's diagnosed by a qualified professional and affects both children and adults.

For some people, yes — consistent background sound can reduce distraction from unpredictable noises and help the brain settle into a task, a technique often used alongside other focus strategies. It works differently for everyone and isn't a treatment for ADHD itself, so if focus difficulties are significantly affecting your life, it's worth talking to a healthcare professional about a full evaluation.

They're all types of steady background sound, but with a different tonal balance. White noise is flat across all frequencies (like TV static), pink noise is softer with more bass and less treble (closer to steady rainfall), and brown noise is deeper and heavier still (like a low rumble or strong wind). Which one feels most soothing is largely personal preference.

For many people, moderate, steady background sound reduces the mental disruption caused by sudden or unpredictable noises around you, which helps maintain focus during study or deep work. Complete silence or overly loud, variable noise can have the opposite effect for some people, so it's worth experimenting to find what works for you.

Calming soundscapes are commonly used as part of relaxation routines, because a steady, predictable sound environment can help the body settle out of a stressed state. They're a helpful complementary tool, not a replacement for professional support if you're dealing with ongoing anxiety.

Most adults need around 7 to 9 hours of sleep per night for good physical and mental health, though the exact amount varies by individual. Consistency — going to bed and waking up at similar times — matters just as much as total hours.

Being physically tired and being able to fall asleep aren't the same thing — falling asleep also requires your nervous system to downshift out of an alert state, which stress, screen stimulation, or an overactive mind can block even when your body is worn out. This lines up with the two-process model of sleep, first described by sleep researcher Alexander Borbély, which separates "sleep pressure" (how tired you are, which builds the longer you're awake) from your circadian rhythm's readiness to actually let you switch off.

For a lot of people, lying down in a quiet, dark room removes the daytime distractions that were keeping racing thoughts at bay, so the mind suddenly has nothing else to do but replay the day or worry about tomorrow. Sleep psychologists — including researchers behind cognitive behavioral therapy for insomnia (CBT-I), the treatment approach endorsed by the American Academy of Sleep Medicine — call this "cognitive arousal," and it's a big reason steady background sound helps some people: it gives the mind something neutral to settle on instead of silence.

In a completely silent room, there's no competing input to distract an anxious or overactive mind, so internal thoughts effectively become the loudest thing in the room. A steady, predictable soundscape can act as a kind of gentle "noise floor" that keeps that internal volume from feeling so overwhelming.

This is a well-documented pattern known as "sleep effort," studied extensively within CBT-I — the evidence-based, first-line treatment for chronic insomnia recommended by the American Academy of Sleep Medicine. The more pressure and attention you put on falling asleep, the more alert and self-monitoring your brain becomes, which works directly against the relaxation sleep requires. CBT-I practitioners often recommend the opposite approach: get out of bed if you're wide awake, do something calm and low-stimulation, and let sleepiness return on its own rather than forcing it.

There's no single "best" — it depends on the person. Rain and other steady nature sounds are the most universally popular starting point, white noise tends to help people who need to mask a noisy environment, and brown noise's deeper tone works well for people who find lighter noise types too "hissy." The most reliable approach is testing two or three types against each other for a few nights each and noticing which one you actually fall asleep faster with.

Yes, for many people — rain is one of the most consistently popular sleep sounds because it's naturally steady and non-repetitive-sounding, which makes it easy for the brain to tune out as background rather than something to keep listening to. Like any sleep sound, it works better for some people than others, so it's worth testing against a few alternatives.

Brown noise is deeper and heavier than white or pink noise, and many people find its low rumble more soothing and less "hissy" for sleep specifically. As with the other noise colors, the evidence is more anecdotal than clinically proven, but it's a low-risk, widely-used option worth testing if lighter noise types haven't worked for you.

Yes — a fan is essentially a real-world source of steady, broadband sound similar to white noise, and it's one of the most common sleep aids for exactly that reason. It also cools the room, which independently supports better sleep, since a cooler bedroom is generally recommended for good sleep quality.

For some people, yes — a calm, familiar voice can occupy the same "racing thoughts" space that background sound does, giving an overactive mind something low-stakes to focus on instead of worry. The tradeoff is that voices and stories engage more of your language-processing brain than instrumental ambient sound does, so they can also keep some people more awake — part of why purely ambient, wordless sound tends to be the safer default for sleep.

Yes, for many people a steady, low-key voice — audiobooks, calm narration, talk radio — can interrupt the loop of anxious or repetitive thoughts by giving your attention somewhere else to go. It works differently from person to person, and some people find it easier to drift off to wordless ambient sound once their thoughts have settled.

Familiarity reduces the brain's need to stay alert and evaluate a new stimulus, so a sound you already associate with rest — rain, a fan, a specific soundscape — can act almost like a learned cue that it's time to sleep. This is part of why building a consistent sleep-sound routine over time tends to work better than switching sounds every night.

Sound is emotionally associative, so a track that reminds you of something stressful — a specific rainstorm, a particular melody, even certain frequencies some people find unpleasant — can trigger tension instead of calm, even if the same sound relaxes someone else. If a sound isn't working for you, that's a sign to try a different type rather than push through it; there's no universally "correct" sleep sound.

The Sleep Foundation and hearing-health organizations like the American Academy of Audiology generally recommend keeping ambient sound around the volume of a quiet conversation, roughly 50 decibels, since higher volumes — especially sustained through headphones — have been linked to disrupted deep and REM sleep. A useful rule of thumb: if the sound would make it hard to hear someone talking normally next to you, it's too loud for sleep.

Unlike sleep, focus sound can sit a bit higher — a widely cited 2012 study published in the Journal of Consumer Research found the sweet spot for boosting abstract, creative thinking was around 70 decibels, roughly the volume of a busy coffee shop. Past that point, louder noise starts working against concentration rather than for it, so "moderate and steady" is a better target than "as loud as possible."

A speaker placed a few feet from your bed is generally the safer choice for overnight use, since it avoids hours of sustained volume directly against your ears, which headphones and earbuds can't avoid. Headphones are fine for shorter use or naps, but for a full night, the American Academy of Audiology and similar hearing-health bodies tend to recommend a speaker instead.

Neither is "correct" — some people sleep better with sound running all night, especially in noisy environments, while others prefer it to fade out once they're likely asleep, often 30 to 60 minutes in. If you're worried about becoming dependent on sound to fall back asleep after a middle-of-the-night waking, fading it out is a reasonable middle ground.

Brown noise for ADHD focus went viral on TikTok and Reddit, with huge numbers of people describing their mental "chatter" suddenly going quiet when they turn it on. The formal research is still thin and mostly anecdotal — a few small studies suggest white and pink noise can help concentration in people with attention difficulties (through a mechanism called stochastic resonance), but there isn't strong direct evidence yet specifically for brown noise. In short: many people report real benefit, but it isn't a scientifically proven treatment for ADHD — it's a tool worth trying, not a fix.

Some people do get used to needing background sound to fall asleep, similar to getting used to a specific pillow. That's not inherently harmful, but it can be inconvenient while traveling or anywhere without your usual sound source. If you'd rather avoid that dependency, using a sleep timer so the sound fades out once you're asleep — instead of playing all night — is a simple middle ground.

The evidence is genuinely mixed. Some studies show white noise helps people fall asleep faster, especially in noisy environments, while other reviews found little consistent benefit and flagged that high volumes can disrupt deep or REM sleep. The safest approach: keep the volume no louder than a quiet conversation (roughly 50 dB) and judge it by how it works for you — it helps a lot of people, but it isn't guaranteed for everyone.

Not necessarily. For sleep, people generally lean toward deeper, slower sounds — brown noise, rain, low rumble — that promote relaxation. For focus, many prefer steadier sounds that mask distractions without pulling attention, like white or pink noise. It comes down to personal preference, so it's worth trying a few different sound types to see what actually works for your brain.

At a safe volume, no — but any sound played too loud for long stretches, especially through headphones overnight, carries a hearing-safety risk. Sleep experts generally recommend keeping ambient sound around the volume of a quiet conversation and using a speaker a few feet away rather than earbuds all night.

It's common in people with and without ADHD. The "stochastic resonance" theory suggests a certain level of background stimulation can help an understimulated brain settle into a task, especially in an otherwise silent, distraction-prone environment. Needing background noise to focus isn't a diagnosis on its own — if attention difficulties are a broader, ongoing pattern beyond just a noise preference, that's worth exploring with a professional.

Not necessarily. For many people — especially light sleepers or anyone in a noisy environment — total silence can make sudden sounds (a car outside, a creaky floor) more jarring, while steady background sound masks those disruptions. Whether silence or background sound works better really is individual, so it's worth trying both.

It's backed by real research, not just a coffee-shop cliché — a well-known study found that moderate ambient noise, around 70 decibels (about the volume of a busy café), boosted creative thinking compared to near-silence or louder noise, because a moderate amount of background stimulation nudges the brain toward more abstract, imaginative thinking. Push past that sweet spot into much louder noise and it starts working against you, so the goal is moderate and steady, not loud.

Body doubling is a technique — common in ADHD communities — where working alongside another person, even silently, helps you start and stay on a task through a quiet sense of accountability and presence. Ambient sound can't fully replace another person, but many people use a steady background sound as a lighter version of the same effect — a consistent "it's work time" cue that helps the brain settle into focus, even without a real body double.

A sudden, sharp alarm can spike your heart rate and trigger a stress response, contributing to sleep inertia — the groggy, disoriented feeling right after waking. Alarms that build gradually in volume, with a melodic rather than a flat repeating tone, appear to ease the transition out of sleep more smoothly and reduce that grogginess.

It can — your brain naturally gets used to a completely unchanging sound, so a track that helped you fall asleep easily for months might start to feel less effective later. Rotating between a few different sounds every so often can help keep the effect from fading.

Knowing what to do and being able to start are two different cognitive processes — task initiation can stall even when motivation and clarity are both present, especially in an understimulated or overloaded state. This is one reason external structure — a timer, a to-do list, steady background sound — helps: it takes some of the "getting started" burden off willpower alone.

Brown noise's deep, heavy tone tends to work better for sleep than for focus, since many people find its low rumble more sedating than energizing. For concentration, white or pink noise is generally the better fit — they mask distraction without pulling you toward relaxation the way brown noise can.

Yes — there's real research behind this, not just a feeling. Systematic reviews of clinical trials have found that music therapy produces a meaningful reduction in anxiety symptoms across settings like hospitals and mental health care. That formal research is studying music therapy delivered by a trained therapist, though; casually listening to calming sound on your own is a lighter, less structured version of the same idea. It can genuinely help you relax and lower stress in the moment, but it isn't a replacement for treatment if you're managing an ongoing anxiety disorder.

There's genuine evidence here too, with an important caveat. Meta-analyses of clinical trials have found that structured music therapy, delivered by a qualified therapist, can meaningfully improve depression symptoms as a complementary approach alongside standard care. Passively listening to calming sound day to day is a different, more casual thing, and many people do find it genuinely helps their mood in the moment — but if you're dealing with depression, sound and music work best alongside professional support, not instead of it.

Music therapy is a specific, regulated clinical practice where a trained therapist designs and delivers sessions tailored to a person's mental health needs — it's what most of the strong research on anxiety and depression is actually studying. Listening to ambient sound or music by yourself is a different, more casual thing: a relaxation and focus tool, not a clinical treatment. Both are genuinely valuable, but they're not interchangeable, and it's worth being honest with yourself about which one you need.

A widely publicized (though industry-commissioned rather than peer-reviewed) study by Mindlab International tested a range of tracks for their effect on anxiety and found that slow, steady tempos — without sudden shifts in volume or rhythm — produced the largest calming effects, a pattern that lines up with more rigorous research on tempo and physiological arousal too. Ambient soundscapes work well for the same reason: they're intentionally steady, without the sudden shifts a song's verse-chorus structure naturally has.

Yes — a widely cited 2013 review by McGill University neuroscientist Daniel Levitin, published in Trends in Cognitive Sciences, found that music listening is associated with measurable reductions in cortisol (the body's primary stress hormone) alongside slower heart rate, which lines up with how people describe feeling physically calmer, not just mentally distracted. It's a real, measurable short-term effect, though it's not a treatment for an underlying anxiety condition.

Grounding techniques — using a steady sensory anchor to interrupt a panic response — are a common recommendation from anxiety specialists and the American Psychological Association, and a predictable background sound can serve as one such anchor alongside breathing techniques. It's not a substitute for learning panic-attack coping strategies from a therapist — if panic attacks are frequent or severe, that's worth bringing to a doctor or mental health professional.

Songs are strongly tied to memory and emotion — researchers studying what's known as "music-evoked autobiographical memory," including work by psychologist Petr Janata at UC Davis, have found that familiar music can vividly resurface the emotional state tied to when you first heard it, even if the melody itself is objectively calm. Ambient soundscapes largely avoid this because they're less likely to carry personal emotional associations, which is part of why some people find them more reliably neutral for anxious or low moods.

For many people, yes — a 2017 study from the University of Sussex, published in Scientific Reports, found that listening to natural sounds like rain and ocean waves shifted the brain into a more relaxed, outward-focused state and was linked to lower physiological stress markers than artificial sound. Nature sound also sidesteps the lyric and melody-memory issues that can complicate music for anxiety, which is one reason it's such a common choice for calming soundscapes.

It can help some people interrupt the loop, similar to how it helps at night. This is consistent with attention restoration theory, developed by psychologists Rachel and Stephen Kaplan, which describes how gentle, non-demanding sensory input — including natural or ambient sound — can help redirect an overtaxed, ruminating mind. It works as a short-term coping tool alongside things like grounding exercises or breathing techniques, rather than as a way to resolve the underlying thought pattern.

Two separate things are going on. First, your brain automatically processes language, so lyrics compete for the same mental resources you need for reading, writing, or falling asleep — researchers studying what's called the "irrelevant speech effect" have found that music with lyrics disrupts memory and reading comprehension more than instrumental music does. Second, familiar or catchy songs are more likely to become "earworms" that loop in your head, and researchers at Baylor University found that people prone to earworms had more trouble falling and staying asleep. Ambient soundscapes sidestep both problems — no melody to loop, no words to process — so they fade into the background instead of competing for your attention.

It really depends on the person. For some, a steady, predictable soundscape gives an anxious mind something calming and non-threatening to settle on, which can help interrupt racing thoughts. For others, especially anyone who finds extra stimulation overwhelming, quiet is more soothing. Neither is universally "correct" — it's worth noticing which one actually leaves you feeling calmer.

No. Even the clinical research on music therapy studies it as a complementary approach delivered alongside standard care, not a replacement for it. Passive listening on your own is a genuinely useful relaxation and mood tool, but if you're managing an ongoing anxiety or depressive disorder, it works best as one part of a broader plan that includes professional support — not instead of it.

Music engages the brain's reward system — brain-imaging studies have shown that music people find pleasurable can trigger the release of dopamine, the same neurotransmitter involved in other rewarding experiences. That's part of why calming sound can shift how you feel in the moment, even before considering any structured therapeutic effect.

A short nap of about 15 to 20 minutes tends to work best for most adults — long enough to reset alertness without dropping into deep sleep, which is what causes that groggy, sleep-inertia feeling if you wake mid-nap. Sleep specialists at places like the Cleveland Clinic note that naps over 60 minutes are more likely to disrupt nighttime sleep, so earlier in the afternoon (before 2–3pm) and shorter is generally the safer bet.

It's more nuanced than the "blue light is the enemy" story suggests. Newer reviews have found that screen use before bed causes, on average, only a modest delay in falling asleep — often cited around ten minutes — and researchers now think what you're doing on the screen (stimulating content, doomscrolling, overall brightness) may matter more than the blue wavelength itself. That said, most sleep researchers still recommend dimming screens and avoiding stressful or stimulating content in the hour before bed, just not necessarily because of the color of the light.

Most sleep researchers recommend stopping caffeine at least 8 to 10 hours before bedtime. A widely cited meta-analysis in Sleep Medicine Reviews put the safe cutoff for an average cup of coffee at around 8.8 hours before sleep, and caffeine's half-life varies a lot between people — some people clear it in a few hours, others take nearly twice as long — so if you're sensitive, cutting off earlier in the day is worth trying.

For many people, yes, as a form of sound masking that makes the ringing less noticeable, especially at night. Hearing specialists often suggest white or pink noise for this, though the evidence is mixed, and a small number of studies have raised concerns about relying on white noise at high volumes long-term. If tinnitus is new, worsening, or distressing, it's worth getting evaluated by a hearing or ENT specialist before building a long-term sound routine around it.

Sleep experts generally advise not fighting it — lying in bed watching the clock tends to spike stress and make it harder to drift off. The common recommendation is: if you're still awake after about 20 minutes, get up, keep the lights low, and do something calm and non-stimulating — reading, quiet ambient sound — until you feel sleepy again, rather than forcing it.

Both can be true — it depends on the kind of noise and the kind of task. Moderate, steady, predictable sound, like a coffee shop or an ambient soundscape, tends to help creative and abstract thinking. Unpredictable, chaotic noise, like a real open-plan office full of conversations and interruptions, has been shown in workplace research to increase stress and push the brain toward reactive, urgent processing rather than the calm, analytical focus that deep work requires. The steadiness and predictability of the sound seems to matter as much as the type of sound itself.

Deep work, a term coined by researcher Cal Newport, describes deliberately structuring your time and environment for distraction-free focus. Flow state, a concept from psychologist Mihaly Csikszentmihalyi, is the immersive, "in the zone" feeling that can happen during that focused work. Newport himself has noted that non-lyrical, non-melodic sound — ambient textures, nature sounds, quiet instrumental music — can help mask distracting noise and support that focused state, as long as it stays quiet enough not to become a distraction itself.
