iPhone alarm clock and sleep tracker
An alarm you cannot quietly lose, and a sleep tracker that tells you the truth. Nothing leaves your phone.
The problem
The app gets terminated in the night. A notification arrives with the ringer down. You swipe something at 6:31 and remember none of it. You do not find out that your alarm did not work until the moment it matters, and by then it is already too late to fix.
Sleepy Banana treats waking up as a job with redundancy, not a single timer and a hope. Every layer knows about the others, and the app checks its own work.
What it does
Your wake-up is layered. The app's own alarm rings first, a chain of scheduled notifications stands behind it, and a system alarm backs the whole thing up. Layered recovery helps restore the alarm after an unexpected termination. No software alarm is infallible. This one refuses to fail quietly.
Stop the alarm by solving a math problem, shaking the phone, typing a phrase, tilting a ball through a maze, counting sheep, matching a face, or scanning a QR code you stuck to the bathroom mirror. An emergency stop appears after repeated failures or 90 seconds, so you are never trapped.
Set a window instead of a moment. The alarm looks for light sleep inside it and wakes you when your body is already close to the surface, rather than dragging you out of deep sleep at exactly 6:30.
Put the phone on the mattress. Movement shapes your night into deep, light and awake. There is no invented REM band, because a phone on a mattress cannot see your eyes, and we would rather show you what we actually measured.
Hear how loud your nights really are. Noise analysis measures loudness on the device and is audio-free. Turn on recordings and short clips are saved to your iPhone only, capped per night, deleted after a week, and deletable at any time.
A catalogue of lullabies and soundscapes, from rain on a canopy to a fireside crackle, plus binaural beats and guided meditation. They fade out on a timer so nothing plays all night.

No account. No analytics SDK. No advertising identifier. Nothing sold, ever.
Questions
That is the entire point of the design. The in-app alarm rings first, a chain of scheduled notifications covers the first minutes if the app is not running, and a system alarm sits behind both as an emergency backup. That said, no software alarm on any phone is infallible, so do not use any app as your only alarm for something critical.
No. There is no sign-up, no login, and no password. The app has never asked for an email address and does not have a server that knows who you are.
On your iPhone. Nights, movements, scores, tags and comments live in a local database. With your permission, nights are also written to Apple Health, which is how your history reaches your other devices. Nothing is uploaded to us.
Only if you ask it to. Noise analysis measures loudness without keeping any audio. Recording snoring is a separate switch. When it is on, short clips of detected sounds are stored on the device, capped per night, and deleted after a week. Recordings never leave your iPhone.
The system-level alarm backup is built on AlarmKit, which Apple introduced in iOS 26. It is the piece that lets an alarm survive the app being terminated, so the app does not ship without it.
No. Premium is a single one-time purchase that unlocks everything permanently. Before you buy, the free preview gives you up to seven nights within seven days, so you can judge the alarm on real mornings rather than on a screenshot.
It can learn the difference. The app analyses snoring sounds on the device and groups them, so a shared bed stops being a mystery. Like everything else here, the analysis happens on your iPhone.
Seven nights free, then one payment if it earns it. iOS 26 or later.
