Sleep tracking that needs nothing but your iPhone. No watch, no ring, no subscription. Pay once, plug the phone in beside your bed, and see your whole night by morning. Pick a sound, set the alarm, put the phone on the charger. Restful does the rest. TRACKED BY MICROPHONE, NOT BY A GADGET Restful listens through the iPhone microphone and builds your night from what it hears. Nothing to charge on your wrist, nothing to pair, nothing extra to buy. The analysis runs on the phone, a minute at a time. Each minute of audio is scored and then deleted on the spot, so no recording is ever kept and nothing is uploaded. FALL ASLEEP TO SOMETHING BETTER THAN SILENCE Four full-length nature tracks: heavy rain and thunder, ocean, a babbling brook, and a lone campfire. Four night-city ambiences: Tokyo, New York, Paris and Shanghai. And a ten-channel mixer you build yourself: ocean, stream, rain, thunder, wind, campfire, crickets, singing bowl, cafe and white noise, each with its own volume slider, all playing at once. Rain with distant thunder and nothing else. A campfire under wind. Your mix is remembered for tomorrow. Set the audio timer to 10, 15, 20 or 30 minutes and the sound stops on its own. Seven animated scenes to fall asleep to, from a mountain night to a passing train. YOUR SLEEP JOURNAL, FROM THE FIRST NIGHT A curve for every night, showing awake, light and deep phases. Sleep score, total sleep, deep sleep, when you drifted off and when you woke up. Save a summary image of any night. THE PATTERN, ONCE YOU HAVE A WEEK OF THEM After seven tracked nights, Insights fills in: 7 days, 4 weeks, 120 days, or everything you have tracked. Average score, average sleep, average deep sleep, nights tracked. Daily trend, average by weekday, and your bedtime and wake-up rhythm on one chart. A short, plain-language suggestion for tonight, drawn from your own numbers. NAP MODE Swipe across to naps. Pick a length from 10 minutes to six hours, pick a sound, and Restful wakes you at the end with the tone you chose. Naps are timed and woken, not scored: the microphone tracking runs overnight only. WAKE UP THE WAY YOU WANT Seventeen wake-up tones, from birdsong to cicadas. Shake the phone to snooze, with your own snooze length and a limit on how long you can keep snoozing. This is a fixed-time alarm. It rings when you set it, and does not move itself inside a light-sleep window. WHAT ONE PAYMENT BUYS You buy Restful once. There is no subscription, ever. No ads. No hardware to buy. No paid tier, so nothing you use today can move behind a paywall later. BEFORE YOUR FIRST NIGHT, HONESTLY Overnight tracking needs the iPhone plugged in and placed near your bed. If the screen stays locked on battery power for about an hour, the session ends and no journal is written for that night, so leave it on the charger. Restful asks for microphone access to analyze your sleep. Sleep estimates built from sound are estimates. A still, quiet hour spent reading can read as sleep. Use them to see your habits over weeks, not as an exact measurement of any single night. Restful does not detect snoring, does not work with an Apple Watch, and does not have a smart alarm. Restful is new and made by a small team, so you will not find a wall of ratings on this page yet. The trends and the nightly suggestion are built only from your own tracked nights, so they get more useful the more nights you keep. Restful is a general wellness app for building better sleep habits. It is not a medical device, and it does not diagnose, treat, cure or prevent any condition. If you have ongoing concerns about your sleep or your health, please talk to a doctor. iPhone and iPad. English, Simplified Chinese, Japanese and Korean. ## Chart rankings - #191 in Top Paid · Health & Fitness (US App Store) ## Version history (last 2 releases) ### 1.0.6 — 2026-09-10 A clearer name, and a listing that finally says what this app does. Restful is now "Restful: Sleep Tracker & Sound" on the App Store. Same app, same one-time price, still no subscription and no ads. It was simply impossible to find under the old name. Also in this version: - A rewritten App Store description. It spells out what Restful does, what it needs from you (the phone charging, near the bed), and what it never does with your microphone: audio is scored a minute at a time and deleted as it goes, so nothing is stored or uploaded. - The description now also says plainly what Restful does not do, because a few of those things were previously implied. There is no smart alarm that hunts for a light-sleep moment, naps are timed and woken but not scored, and snoring is not detected. - Maintenance and stability work across sleep tracking, nap mode, the sound library and the alarm. Thank you for using Restful. If it has helped your nights, a rating on the App Store makes a real difference to a small independent app. ### 1.0.5 — 2026-05-11 No release notes. ## More apps by Curastone CORP. - [Lets: Gathering at first sight](https://appshunter.io/ios/app/lets-gathering-at-first-sight/id1632932052) - [KnoWhiz](https://appshunter.io/ios/app/knowhiz/id6670285646) All apps by Curastone CORP.: https://appshunter.io/developer/1609919101 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
