iPhone
Schlummer is a sleep tracker app for iPhone that combines sleep-stage analysis, a gentle smart alarm, and on-device snore and sleep-talk recording in one app, plus 12 built-in sleep soundscapes. The smart alarm wakes you during light sleep inside your chosen window, and every night gets a readable sleep curve and a sleep score. Everything runs on your iPhone with no account and no cloud, so your sleep data never leaves your device. A banner and an occasional full-screen ad keep the free version going, and Schlummer Pro removes them.
WAKE UP GENTLY, OR NOT AT ALL
The smart alarm wakes you during light sleep inside your personal window so you start the day more rested. Snooze works even in gentle-wake mode. Pick your own alarm sound: three built-in tones, any song from your music library, or an audio file. It fades in gently rather than jolting you awake. And if you only want to see how you slept, switch the alarm off entirely and Schlummer simply measures your night.
UNDERSTAND YOUR NIGHT
A beautiful, readable sleep curve and a sleep score show how your night went at a glance. We treat the numbers as a wellness trend, not a medical measurement.
HEAR WHAT YOU DO AT NIGHT
Snoring and sleep-talk are recorded on-device only at loud moments. Play them back in the morning, tag a partner, and share as a video with a waveform. Rather not record anything? Switch it off: your sleep stages keep working and nothing is written to your iPhone.
FALL ASLEEP CALMLY
12 on-device generated soundscapes (rain, ocean, wind and more) with a sleep timer.
SEE EVERY NIGHT
The Morning tab keeps your nights in one list with a score trend. The free version holds the last seven nights; Schlummer Pro keeps the whole archive and the long-term trend.
HONEST, NOT GREEDY
The smart alarm, your own alarm sound, snore recording, your sleep score and sharing a night as a video are free. Schlummer Pro adds your full night archive, the long-term trend, all 12 soundscapes and removes the ads: monthly, yearly, or a one-time Lifetime with no subscription. We never raise the price on features you already own.
PRIVATE BY DESIGN
No cloud and no account. Your sleep data never leaves your iPhone, which is what makes Schlummer GDPR-friendly. Ads are delivered by Google AdMob and you are asked for consent first; Schlummer Pro removes them.
Note: Schlummer is a wellness product, not a medical device. For a reliable alarm we recommend charging your iPhone overnight and keeping the ringer on.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Three things you asked for.
TURN THE ALARM OFF
Switch "Wake me up" off and Schlummer only measures your night. No alarm, no notification. Tap End when you wake up.
BRING YOUR OWN ALARM SOUND
Three new built-in tones, or pick any song from your music library or an audio file. Your tone fades in gently over about half a minute instead of jolting you awake.
TURN SNORING RECORDINGS OFF
Sleep stages keep working and nothing is written to your iPhone.
SEE EVERY NIGHT, NOT JUST THE LAST ONE
The Morning tab now has a list of all your nights with a score trend. The free version holds the last seven.
ALSO FIXED
- The alarm no longer rings immediately when a night starts after your set wake-up time.
- When microphone access is off, Schlummer now says so instead of quietly measuring nothing.
- Nights shorter than half an hour no longer get a made-up score.
- Your wake time, wake window and alarm sound are remembered between nights.
