Afterbeat

Private rhythm log, on device

Free · Designed for iPhone. Not verified for macOS.

Free while I find out whether this is useful to anyone. On-device only: no account, no server, no analytics. Blunt feedback welcome. Afterbeat records a private session on your Apple Watch and gives you a clear summary afterwards. You start and stop by hand on the watch. When you finish you get duration, rhythm, motion intensity, and, if heart rate is available, how quickly it settles down afterwards. Everything stays on your devices. No account, no sign-in, no server, no analytics. History is kept in a local file on the watch, with an optional mirror on your iPhone over the paired-device connection. You can delete a session from either device, and saving to Apple Health stays off until you turn it on. What you see after a session: - Duration and active time - Average and peak rhythm, in RPM - Peak motion intensity - Rhythm steadiness and variation - Heart rate and how fast it comes down, when real samples exist - One closing line, dry by default, playful if you prefer Afterbeat measures wrist motion. It is not a medical app, it does not diagnose anything, and it does not rate your body. An Apple Watch is required. Recording happens on the watch; the iPhone app is for reviewing history.
