Something not working, or an idea for what it should do next? Write to support (at) sleepdrift.app and a person will answer.
When you write in, it helps to include:
your iPhone model, your iOS version, and — if a sound came out wrong — the exact words you typed.
Open the Create tab, type what you want to hear, and tap go. Describe the place and the material, not just the thing: “rain on a canvas tent” beats “rain”, and “box fan in a big empty room” beats “fan”. The first sound of a session takes a moment longer while the engine warms up.
Try rewording rather than repeating. The generator responds to texture and setting, so adding a surface (“on a tin roof”, “through pine trees”) or a distance (“distant”, “close”) usually changes it more than adding adjectives. Every sound also has more than one take — replay it to drift between them.
Check the phone is not in silent mode, and that the volume slider in the app is up — it follows the system volume. Playback continues with the screen off by design; if it stops, make sure Low Power Mode is off and that another app has not taken over audio.
Sleep tab → set a timer. It fades out slowly rather than cutting off. If you also set a gentle wake time, your morning sound rises from a whisper over about two minutes.
Guidance for infant sleep puts all-night sound under roughly 50 dB, with the speaker across the room rather than beside the cot. Sleep Drift does not try to measure that — a phone cannot do it reliably, and a wrong number about a baby’s hearing is worse than no number. The practical test: if you have to raise your voice over it, it is too loud.
You are on an older version. Versions 1.1 and 1.2 were free to download and capped playback at five minutes once a free night had run out. SleepDrift is a paid app now and nothing is limited: update from the App Store and sounds play until you stop them or the sleep timer fades them out. Nothing you have already made is affected.
First, update to the current version from the App Store — updating is free, and if you already have SleepDrift it stays yours. SleepDrift is a paid app now: there is no paywall and no in-app purchase, so once you are on it nothing inside the app can ask you for money. Versions 1.1 and 1.2 did have one, and on those a purchase that has not been recognised brings it back, so updating is the fix. If the App Store itself asks you to buy, it is signed in to a different Apple Account from the one that bought the app: switch accounts and re-download from your purchase history. Nothing you have made is ever deleted.
SleepDrift no longer sells a subscription. Update to the current version before you cancel: updating is free, and the current version is a paid app with nothing to unlock, so cancelling then changes nothing for you. On 1.1 and 1.2 it does matter — those versions fall back to five-minute playback when a subscription lapses. To cancel, go to Apple at apps.apple.com/account/subscriptions; we cannot do it for you and neither can the app. Nothing you have made is ever deleted.
There is nothing held anywhere but your device, so deleting the app deletes everything. See the privacy policy.
