StatGrove: Sleep Cycle Tracker

About this app

Know when your body is ready
Every morning, Recovery hands you a single number, 0 to 100, that tells you how recovered you are. It's built from last night's HRV, resting heart rate, and sleep, and it's judged against your own 60-day baseline, not some average stranger's. The score ticks down as the day wears on and you spend energy, so you can feel out whether it's a day to push or a day to ease off. Insights that learn your habits
This is where it gets interesting. StatGrove studies your own mornings and nights, then starts telling you what actually moves them. Longer sleep lifts your score. A late workout costs you. A steadier bedtime pays off. None of it is generic advice: these are patterns found in your data, and they keep getting sharper the longer you use it. Understand your sleep
Every night broken into its stages and efficiency, one night at a time. Each evening you get a short list of personal aims for a better night: when to turn in, what to keep steady. Not a checklist, not a guilt trip. Just what your own nights say works. And a dashboard for everything else
Steps, active energy, heart rate, VO₂ max, workouts, and more: 23 metrics you can drop in as tiles, size how you like, and read at a glance. Put any of them on your Home and Lock Screen as widgets. Every tile shows this week against last, and you can scroll back through months of history and drag across any chart for an exact value. Your data doesn't leave your phone
Nothing gets collected, nothing gets sold. There's no login because there's nothing to log into. Your health data stays where it already is. Works best with an Apple Watch or another tracker feeding data into Apple Health. LICENSED APPLICATION END USER LICENSE AGREEMENT https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Lab is new, and it is the reason for this release. Pick one thing to change at night. Commit to how many nights before you start. StatGrove watches, and at the end it tells you whether it helped. If your nights could not answer the question, it says so rather than inventing an answer. LAB • Two, three or four weeks. One question at a time. • Answer each night with a tap, on your phone or your wrist. • Miss a night and it is simply left out. Nothing is held against you. APPLE WATCH • Your morning readiness, last night, and your own metrics. • Complications for your watch face. • Answer tonight’s question without reaching for your phone. TODAY • A dated page now, with your morning score and the night behind it side by side. • Page back through past mornings. • A calmer, more consistent look across the whole app. ALSO • Notifications no longer go quiet later in the day. • Restore Purchases now tells you what happened. • Steadier charts, and a good number of small fixes. Thank you for using StatGrove!

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
