Train inside your
heart-rate zone.
Build interval workouts by zone, send them to your wrist, and stay exactly where you want to be — with live haptic alerts the moment you drift out.
Five live zones
Recovery to Max Effort, computed from your max heart rate and reflected live in color, haptics, and copy on your watch face.
Build your plan
Pick HIIT, Endurance, or Recovery, or build custom intervals — name each block, assign a zone, set a duration, preview the timeline.
Live on your wrist
A big glanceable BPM number, your current interval, and a full-screen color field — on target or not, at a glance.
Never drift out
Stray outside your target zone too long and ZonePulse gives your wrist a haptic nudge and a notification.
Know how you did
Time-in-zone breakdown, heart rate, calories, and distance after every workout — saved straight to Apple Health.
Arabic-first
Full right-to-left Arabic and English support, switchable instantly from either the phone or the watch.
No account. No cloud. Just your zones.
Every workout stays on your own iPhone and Apple Watch — nothing is uploaded anywhere.
