ZonePulse - Heart Rate Zones

ZonePulse turns your Apple Watch into a focused heart-rate-zone training tool — plan your workout on your iPhone, run it on your wrist, and stay exactly where you want to be, zone by zone. TRAIN BY ZONE, NOT JUST BY NUMBER ZonePulse computes five live intensity zones — Recovery, Endurance, Tempo, Threshold, Max Effort — from your max heart rate, and keeps your watch screen, colors, and haptics locked to whichever one you're actually in. BUILD YOUR WORKOUT BEFORE YOU START Pick a preset (HIIT, Endurance, Recovery) or build your own interval plan: name each block, assign it a target zone, set its duration, and preview the whole session on a timeline before you send it to your watch. LIVE ON YOUR WRIST Once you start, your watch shows a big, glanceable BPM number, your current interval, and a full-screen color field that tells you at a glance whether you're on target — no squinting at tiny numbers mid-sprint. NEVER DRIFT OUT OF ZONE Stray outside your target for too long and ZonePulse gives your wrist a haptic nudge and a notification, so you can adjust your pace without breaking stride. KNOW HOW YOU DID After every workout, see exactly how much time you spent in each zone, plus heart rate, calories, and distance, then save it straight to Apple Health, or discard it with a press-and-hold. YOUR HISTORY, ON YOUR PHONE Every saved workout lives in a simple history list on your iPhone. No account required, nothing leaves your device. ARABIC-FIRST, TRULY BILINGUAL ZonePulse ships with full Arabic and English support, including right-to-left layout, switchable instantly from either screen. Requires a paired Apple Watch (watchOS 11 or later) to record workouts; the iPhone app is used to plan sessions, monitor live stats, and review history.
