What’s New Version 1.6
• Added a Workout History & estimated fat-burn tab on iPhone (weekly / monthly / cumulative + charts)
• Unified Direct bpm mode with sliders
• Direct bpm defaults now derive from estimated HRmax
• Streamlined the profile screen
Description
FatBurn Watch helps you stay in your fat-burn heart-rate zone during cardio workouts at the gym.
Set your profile and target zone on iPhone, then start a workout on Apple Watch. When your heart rate stays above the upper limit, the Watch alerts you with haptics, sound, and an on-screen warning so you can ease back without staring at the screen.
Key features
- Start and stop workouts on Apple Watch
- See real-time heart rate during a session
- Estimate HRmax from age (Fox or Tanaka formula)
- Tune target zone (% of HRmax or Direct bpm) and alert sensitivity
- Mute alerts for short breaks
- Save workouts to HealthKit
Privacy
Heart-rate and workout data stay on device and in HealthKit. FatBurn Watch does not send this data to external servers, track you, show ads, or use third-party analytics.
Important
FatBurn Watch is not a medical device. It is a heart-rate feedback tool for workouts and is not intended to diagnose, treat, or prevent any medical condition. Consult a physician if you have health concerns.
