Wear your Apple Watch — or just put your iPhone on the mattress. Wake in a lighter stage near your alarm, and see the stages, HRV and trends behind every night. SleepTracker records your sleep automatically with an Apple Watch — or with just your iPhone on the mattress — and turns the night into a clear picture of your stages, heart rate, and recovery. No setup, no account, nothing to configure. No account. No sign-up. No email. No ads. Open it, allow Apple Health, and go to bed. HOW IT WORKS • Wear an Apple Watch to bed and open the app — sleep stages, heart rate, HRV, and breathing sync straight from Apple Health • No watch? Set your iPhone on the mattress and tap Track Sleep with iPhone — it uses movement and sound to estimate your night • Numbers match the Apple Health app exactly, down to the minute WHAT YOU GET • Sleep rings that show Sleep, Quality, and Deep at a glance • Full stage breakdown — Deep, REM, Light, and Awake • Bedtime, wake time, time to fall asleep, and sleep efficiency • Readiness, Sleep Fuel, and Recovery scores built from your real HRV • Heart rate, HRV, SpO2, and respiratory rate with Apple Watch • A smart alarm that wakes you in a lighter stage near your target time • Sleep consistency, trends, history, and a calendar of every night • Tags for caffeine, late meals, workouts, and stress, so you can see what actually changes your sleep BUILT BY ONE PERSON I built SleepTracker for myself, in a year when AI finally made something like this achievable alone — then kept building whatever people asked for. No team, no investors, and no roadmap written by anyone but the people using it. And no subscription: sleep data you already own shouldn't be rented back to you month after month. YOUR SLEEP DATA STAYS ON YOUR PHONE Sleep and health data is read from Apple Health only after you allow it. Microphone audio is analyzed on your device and is never recorded, stored, or uploaded. There is no account to create and no profile to sell. No tracking of you across other companies' apps or websites, and nothing shared with data brokers. TELL ME WHAT TO BUILD See something in another sleep app that you wish this one had? Email mark@vibecode.review. I read every message and I build what people actually ask for — that is how most of this app got here. Sleep better by understanding your nights, automatically.

Apple Health, fixed and finished. - Connect Apple Health now works properly and asks for permission as it should. - The app tells you what happened every time you connect or sync, instead of leaving you on a screen that never changes. - Nights you track with your iPhone are now saved to Apple Health, so they show up there and in your other apps - no Apple Watch needed. - When a night is recorded by both your Apple Watch and your iPhone, the Apple Watch reading is the one you see.
