iPhone Giveaway of the Day - Chest Strap HR Monitor

Train in your heart rate zones using your Bluetooth chest strap — no smartwatch required.

Strap Zone connects directly to your heart rate monitor and shows real-time zone data on your iPhone. Perfect for zone 2 training, fat burning workouts, HIIT, or any heart rate-based training.

WHY CHEST STRAP + PHONE?
Chest straps are 99.6% accurate — far more reliable than wrist-based monitors. But most zone training apps require an Apple Watch. Strap Zone doesn't. Just your phone and your strap.

FEATURES

Real-Time HR Zones (Z1–Z5)
See your current zone with bold, color-coded display:
Z1 Recovery | Z2 Endurance | Z3 Tempo | Z4 Threshold | Z5 VO2 Max

Zone 2 Training Made Simple
Stay in your target zone for aerobic base building, fat burning, and longevity training. Audio alerts keep you in the zone without looking at your screen.

Structured Workouts
Build custom interval workouts with target zones, repeat blocks, and timed segments. Perfect for HIIT, threshold training, or guided zone 2 sessions.

Time-in-Zone Tracking
See exactly how long you spent in each zone during and after your workout.

Workout History
Review past sessions with detailed zone breakdowns and heart rate data.

Optional GPS + TCX Export
Record route, distance, pace splits, and export a complete TCX file for platforms like Strava, Garmin Connect, and TrainingPeaks. GPS can be turned off anytime in Settings.

Large, Clear Display
Big BPM numbers easy to read during any workout — on the treadmill, bike, or gym floor.
