OpenStrap edge v0.4.4
Band gestures (new) — map a double-tap to an action in Profile → Gestures: play/pause, next, previous, volume up/down (Android), ring my phone, flashlight, mark a moment (journal tag), and start/stop workout. The picker only offers what your platform can actually do (e.g. media control isn't shown on iOS, where it can't reach third-party players).
Connection resilience — reconnect now keeps trying for as long as a session is active (not just ~30 s), and a full backlog drain runs on reconnect, on background wake-ups, and when a workout ends. A phone-free run or a night away from your phone is now recovered from the band's flash instead of being silently lost.
Honest workouts — a session with no heart-rate coverage now shows "No data" with an explanation, instead of a misleading "0.0 strain · 0 bpm".
Sleep "Consistency" — the sleep-regularity metric is labelled honestly (circular variance of your bed/wake times); it no longer claims to be the Phillips Sleep Regularity Index.
Low-battery & charging notifications — get an OS notification when the band is low or on the charger.
APK is signed (Android, supports in-app OTA). The iOS .ipa is unsigned — sideload only (AltStore/Sideloadly/TrollStore); a free-account re-sign breaks the App Group, so the widget/Live Activity may not work.
