You already own the hardware. SleepStats unlocks it. Your Apple Watch quietly measures your heart rate variability, resting heart rate, breathing, sleep stages and every workout — then Apple shows you a wall of raw numbers and no answers. SleepStats reads that same data and tells you the three things you actually want to know each morning: • How well did you sleep? • How recovered is your body? • How hard should you go today? No extra band. No $300 ring. No monthly hardware rental. Just the watch already on your wrist. — SLEEP SCORE — A single 0–100 score for last night, with the full breakdown: deep, REM, core and awake stages, efficiency, restfulness, and how your heart and breathing behaved while you slept. Finally know if that "8 hours" was actually any good. — RECOVERY — Every morning, SleepStats compares last night's HRV and resting heart rate to your personal baseline and scores how recovered you are. Green means go. Red means your body is asking for a lighter day — before you feel it. — BODY BATTERY — A live energy reserve that drains as you spend and recharges as you rest, right from your wrist. Glance at your Lock Screen and know if you've got another set in you — or if it's time to clock out. — STRAIN & DAY TYPE — SleepStats reads your day's exertion and gives you a target, plus a simple Day Type — Green, Yellow or Red — so you train hard when you're ready and back off when you're not. Stop guessing. Stop overtraining. — THE ALMANAC — Your nights, charted. A beautiful 6-month calendar of every sleep score, your trends, your consistency, your sleep debt, and how many Elite nights you've stacked this month. — ON YOUR WATCH — Native Apple Watch app and complications: see your Sleep Score, Recovery and Body Battery on your watch face. Widgets for your Lock Screen and Home Screen too. — SMART BEDTIME — SleepStats calculates how much sleep you actually need tonight based on your debt and the day you had, then reminds you when to wind down. Built for people who already wear an Apple Watch and want WHOOP-grade insight without renting more hardware. SleepStats Premium unlocks Recovery, Body Battery, Strain coaching, the full Almanac and advanced sleep analysis. — Subscription — SleepStats offers a monthly and annual subscription with a free trial. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the period ends. Manage or cancel anytime in your App Store settings. Terms: https://sleepstats.app/terms Privacy: https://sleepstats.app/privacy Your data stays on your device and in Apple Health. SleepStats never sells your health data.
