StatGrove: Sleep Cycle Tracker

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.
