OpenSleep vs SleepKit

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. PRIVATE BY DESIGN • No account and no sign-up • Sleep analysis happens on your iPhone • Open source: anyone can read the code Available in 22 languages. Sleep tracking is free. The AI Sleep Coach is a one-time purchase with no subscription. OpenSleep is a wellness tool, not a medical device. Talk to a doctor about any sleep or health concerns.

SleepKit measures your night and tells you what it actually knows. TRACK WITH YOUR IPHONE — OR YOUR WATCH Put your iPhone on the nightstand and SleepKit records the night: how long you slept, how restless you were, when you drifted off. Wear an Apple Watch and it uses the watch's measured sleep stages instead of an estimate — automatically, with nothing to set up. HONEST ABOUT WHAT IT MEASURES Every night carries a badge: measured on your watch, or estimated by your phone. Tap it and SleepKit explains what an iPhone on a nightstand can and cannot see — someone else in the bed, a loud room, a night too short to show a pattern. If a night came out wrong, you can correct the times or leave it out of your averages. WHAT YOU GET EVERY MORNING • Sleep score with the full formula shown — no hidden weighting • Sleep stages across the night: deep, REM, light, awake • How long you took to fall asleep, and your sleep efficiency • Snoring detection with recordings you can listen back to • Room noise in decibels FROM APPLE HEALTH Heart rate and its overnight dip, HRV, blood oxygen, breathing rate and wrist temperature — each shown next to your own weekly average, with a plain answer to whether it is normal for you. WAKE UP GENTLY The smart alarm looks for a light sleep phase inside your wake window, so you are not pulled out of deep sleep. If no light phase comes, it still rings at your latest wake-up time. That time is a guarantee, not a suggestion. ON YOUR WRIST AND HOME SCREEN Start or end the night from the Apple Watch app. Widgets show last night's score on the home and lock screen. A Live Activity keeps the running night on your lock screen, so you always know it is recording. STILL EVERY SLEEP SOUND Rain, waves, fire, white noise, city and nature — mix up to eight sounds, save your own mixes, set a fade-out timer. Nothing from the sound library was removed. FREE TO TRACK Recording your night, the score, the stages and the vitals are free and unlimited. Premium adds history beyond 14 days and widgets. PRIVACY Night recordings stay on your iPhone and are never uploaded. No third-party analytics, no advertising, no account.
