Sleep, staged on your iPhone
Set the phone on your mattress, plugged in. MindOS reads four sleep stages from the motion sensor and an inaudible tone. No wearable, nothing recorded, nothing uploaded.
MindOS reads how you slept, your morning HRV, and your screen load, then hands you one honest number every morning: how ready you are for the day. No strap. No account. All on your iPhone.
70, up 6 from your 14-day norm. Stronger morning HRV, well above your usual.
Wearables read your body. None of them read your day: the hours on screen, the late-night doomscroll, the cognitive load that actually drains you. That signal is sitting on the phone in your pocket right now.
MindOS reads it there, alongside your sleep and your heart, and turns the whole picture into one number you can act on. The wearable you were going to buy is the one you already own.
How the read worksA minute of setup, then it works while you sleep and reads your morning in seconds.
Set the phone on your mattress, plugged in. MindOS reads four sleep stages from the motion sensor and an inaudible tone. No wearable, nothing recorded, nothing uploaded.
Rest a finger on the rear camera. MindOS measures heart rate and HRV, RMSSD, SDNN, pNN50, and respiration, and explains every one in plain language so the numbers actually mean something.
A recovery score from 0 to 100, banded Low, Fair, or Primed, built from your sleep, your morning HRV, and your screen load. A plain-English line tells you what moved it and why.
The number is banded and explained, never a bare grade. Tap a state to feel how the morning reads.
In line with your norm. A steady day, no need to push or pull back.
One readiness number, 0 to 100, banded Low, Fair, Primed, with a plain line on what moved it.
Four stages from motion and an inaudible tone. No band on your wrist, nothing leaving the phone.
A 60-second camera reading for HR, RMSSD, SDNN, pNN50, and respiration, each explained.
Your phone use becomes a daily load signal that feeds recovery. A measure of demand, not a scold.
A forward look at where your recovery is heading, computed on your device when there is enough history to be honest.
Glance at your score from the Home and Lock Screen, or share a clean card built from your own numbers.
A wake window that nudges you up near a lighter stage of sleep, then logs the morning into your score.
Log a nap, keep a streak, and watch the two-week calibration sharpen the read to your own baseline.




No account, no sign-in, no servers, no analytics, no ads. Your sleep, heart, and screen data are processed on your iPhone and stay there.
When a signal is missing, MindOS says so instead of inventing one. A two-week calibration learns your baseline and tells you where it is in the process.
MindOS is a wellness app, not a medical device. It does not diagnose or treat anything, and its readings are estimates from phone sensors, not clinical measurements.
The daily read is free forever. MindOS Pro adds the patterns and the forward look, with a two-week free trial.
Free to download. Pro is an auto-renewable subscription billed through your Apple Account, and renews unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings.
No strap to charge. No account to make. Just the phone you already carry, reading your recovery every morning.
