Supercomp

Training is the stimulus. Growth happens in recovery. Supercomp answers one question each morning: should you train today? Train, hold, or rest, with a confidence value and the three numbers behind it. That's the whole app. There's no dashboard, no feed, no streaks, and nothing to scroll. IT READS WHAT YOUR WATCH ALREADY RECORDS Overnight heart rate variability, resting heart rate, sleep, respiratory rate and wrist temperature, compared against your own baseline rather than anyone else's averages. A 28-day rolling baseline, a three-day window for what's happening now, and a weighted score you can inspect line by line. THE METHOD IS PUBLISHED Every weight, threshold and rule is written up in plain English and shipped alongside the app. Tap the numbers on the screen and you can check the arithmetic yourself, for today. Nothing is hidden behind a login. IT SAYS WHAT IT DOESN'T KNOW Supercomp reads recovery markers, not training logs, so it has no idea what you actually did in the gym. When that matters, after a long run of green days, it tells you, instead of implying an authority it hasn't earned. NOTHING LEAVES YOUR DEVICE No account, no sign-in, no servers, no analytics, no tracking. Supercomp performs no networking at all and works in airplane mode forever. PAY ONCE Everything is unlocked for your first fortnight. After that the verdict and its three numbers stay free, and a single purchase adds lock-screen and home-screen widgets, a morning notification computed on device before you wake, verdict history, and the ability to switch training style as your training changes. The style you pick at setup is yours to keep either way. There is no subscription. An app you never open shouldn't charge rent. Requires an Apple Watch worn overnight for the recovery data. Wrist temperature needs Series 8 or later. Supercomp is a training aid, not a medical device, and does not diagnose or treat anything.
