Schlummer
Read full descriptionHide full description
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. Sleep analysis runs on your iPhone without an account, and your sleep data stays on 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 account is needed for sleep tracking. Your sleep data stays on your iPhone. 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. SUBSCRIPTION DETAILS Schlummer Pro is available as an auto-renewable subscription: Monthly (4.99 EUR per month) or Yearly (29.99 EUR per year, approx. 2.50 EUR per month, includes a 3-day free trial). A one-time Lifetime purchase (69.99 EUR) is also available and is not a subscription. Payment is charged to your Apple Account at confirmation of purchase. A subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
