About 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. Use it for zone 2 sessions, HIIT, intervals, or other heart-rate-based training.
WHY CHEST STRAP + PHONE?
Chest straps provide reliable heart-rate data during workouts and are often more responsive than wrist-based monitors. 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
Use zone 2 sessions to organise steady aerobic training. Audio alerts tell you when your measured heart rate leaves the target zone, so you do not need to watch the 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 APPLE HEALTH EXPORT
Off by default. If you opt in, Strap Zone can write your completed workouts and the recorded data you select to Apple Health: heart rate, estimated active energy, distance and GPS route, when system permissions allow. Strap Zone never imports health data from other apps.
Large, Clear Display
Big BPM numbers easy to read during any workout — on the treadmill, bike, or gym floor.
COMPATIBLE BLUETOOTH HEART RATE SENSORS
Strap Zone is designed for sensors that broadcast the standard Bluetooth Low Energy Heart Rate Service. Compatibility is model-specific. Our public evidence matrix documents the current status for Polar H10, Garmin HRM-Dual, Wahoo TICKR and other named models:

Compatible watches may also connect when they broadcast the same service. Availability varies by model.
SIMPLE BY DESIGN
Optional GPS when you want route export. No account. Just heart rate zones — done right.
Your heart rate and GPS route data stay on your device unless you export them yourself. No account.
Works on iPhone, iPad (with Split Screen support), and Mac with Apple Silicon.

Latest updates
3.21.18
Your route map is back: after a GPS workout, your zone-colored route appears on a dark street map again. See your Strap Zone Pro plan in Settings, switch from a trial or yearly plan to lifetime, or restore purchases. If Bluetooth is blocked or off, the app shows a button to fix it and scans again when you return. The summary heart-rate graph now skips paused time and no longer joins pauses or signal gaps with a line.
3.21.13
- Your renamed workouts now show their custom names in CSV exports for Excel and Numbers.
- The new What’s New screen explains updates. You can reopen it anytime from Settings.
3.21.11
See your heart rate over the last 5 minutes with the new live graph. Tap the top-right menu during a workout to switch views and choose which metrics to show. Your choices are shared with Settings and saved for future workouts.
