OpenSleep: Sleep Tracker & AI
Offline AI coach, no wearable
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: a faster on-device AI Sleep Coach and redesigned sleep charts. Track your sleep stages without a wearable. Your sleep data stays on your phone.
OpenSleep tracks your sleep stages without a watch or ring, and explains them with an AI sleep coach that runs entirely on your iPhone.
TRACK SLEEP WITHOUT A WEARABLE
Choose how your phone listens to the night:
• Sonar (contactless): leave your iPhone on the nightstand. OpenSleep uses ambient sound levels to pick up sleep cues. Raw audio is never recorded or stored.
• Mattress mode: place your iPhone flat on the mattress next to your pillow and let the motion sensor follow your movement.
SEE EVERY STAGE OF YOUR NIGHT
• Awake, REM, light and deep sleep, shown on a stage ring and a full-night sleep pattern chart
• Bedtime, wake-up time and total sleep for every session
• History with day, week, month and year views to spot trends
AN AI SLEEP COACH THAT STAYS ON YOUR PHONE
Ask about your sleep, your routine or why you wake up tired. The coach is a large language model that runs on your device, so your questions and answers are never sent to a server. Download the model once, then chat even with no connection.
WORKS WITH APPLE HEALTH
OpenSleep writes your sleep sessions and stages to Apple Health and can show sleep already recorded there.
