RestUp: Sleep Recovery Tracker

Your smartwatch or ring measures you all night. RestUp turns that into one clear answer each morning: go hard today, or take it easy. RestUp is a sleep tracker and recovery app for Android. You wake up to a readiness score from 0 to 100 and a plain line like "Your body is ready for a big day" or "Your body is asking for rest today." It reads your sleep and heart data from Health Connect, so it works with the watch, ring or fitness tracker you own. If you've been sleeping with your watch or ring on, RestUp reads your last 30 days the first time you open it, and you get your first reading today. KNOW WHEN TO PUSH AND WHEN TO REST • See your readiness, sleep, resting heart rate, HRV and VO2 max at a glance, each with a small graph against your usual. • Tap a workout, your steps or a nap to open its own page. See how you sleep after that evening spin class. MAKE SENSE OF A BAD NIGHT • Get a sleep score and a night graph you can read without a manual. On nights your tracker records sleep stages, RestUp explains REM, deep and light sleep in plain words. • See how long you took to fall asleep, how often you woke, and what your heart, breathing and blood oxygen did overnight, when your device saves them. • Insights: tell RestUp what keeps going wrong, like waking at 3 am. It checks your nights for what went along with it, such as late workouts, long naps or travel, and shows a link only after confirming it in your data. FIND WHAT HELPS YOU SLEEP • Track your sleep debt, tonight's target and a wind-down time, with a nudge when it's time to start. • Night experiments (beta): pick one change, like a cooler room or no coffee after 2 pm. Stick with it for 14 nights and RestUp tells you whether it helped. THE MATH BEHIND RESTUP RestUp keeps the screen calm on purpose. Underneath, it: • Reads 11 kinds of health data, including VO2 max, blood oxygen and HRV, the tiny variation between heartbeats that shows how recovered you are. • Builds readiness from five parts: sleep balance, recovery, HRV balance, training load and sleep regularity. • Measures your heart against your own 14-night baseline, so "normal" means normal for you. • Tracks sleep debt with a model from sleep research. A lie-in pays back a quarter of the extra sleep, so a long Sunday sleep won't erase a short week. Sorry. • Works out your chronotype (lion, bear, wolf or dolphin) from when you sleep on days off. LOOK BACK OVER WEEKS AND MONTHS • Findings about how you're wired, like social jet lag and sleep regularity, with the nights behind each one. • Vitals trends over up to six months, each marked improving, steady or shifting. • Every Sunday you get a Weekly Digest: five pages on your week and one thing to try next. • RestUp writes a new Almanac chapter every two months, laid out like a printed book. • You earn Keepsakes, little characters you collect, for your best nights and steadiest streaks. ON YOUR HOME SCREEN • Widgets for your readiness, last night's sleep and tonight's plan. WORKS WITH HEALTH CONNECT RestUp is a sleep tracker for your phone.
