Sleeper: AI Sleep Recorder

Sleeper — Smart AI Sleep Recorder
Ever wondered what actually happens in your bedroom at night? Sleeper records only the essential moments of your sleep and instantly identifies sound types using built-in AI: snoring, sleep-talking, coughing, laughter, and more. Pair it with delayed monitoring and fall asleep to soothing nature sounds or curated sleep music.

• Sleep Music
Explore vast, regularly updated playlists specifically curated to help you relax and drift off.

• Total Privacy — 100% Offline
Your audio recordings never leave your device. They remain private and secure on your phone.

• Intelligent AI Monitoring
Powered by TensorFlow Lite, the neural networks run directly on your device without any cloud services.

• Fall Asleep Effortlessly
Create your own lullaby: mix relaxing nature sounds to unwind before bed.

• Energy Efficient & Convenient
Minimal battery consumption and an automatic morning shut-off schedule.

• Space-Saving Recordings
Sleeper only records when sound is detected, eliminating giant files filled with hours of silence. Customize the sensitivity to your liking — from soft breathing to loud snoring, or from sleep-talking to nighttime coughing.

• Delayed Start
The delayed start timer ensures you don't record the rustling and tossing and turning that happens while you're falling asleep.

• Smart Music Integration
Automatically pauses other media apps before sleep monitoring begins.

• No Internet Required
The app works entirely offline and never transmits your data. Your privacy is guaranteed.

• Effortless Management
Browse recordings by date, delete single entries with a swipe, or clear your entire history in one tap.
