Heart Control: Chest Strap HRM

Heart Control is a Bluetooth chest strap and heart rate band monitor for BLE HRM belts.

Wear a BLE chest strap (heart rate chest band / HRM belt) and connect over Bluetooth Low Energy. Heart Control works with external heart rate sensors that expose the standard Heart Rate Service. It records live BPM and, when your strap provides beat-to-beat data, RR intervals for long sessions, training, and everyday wellness monitoring.

MADE FOR BLE CHEST STRAPS AND HR BANDS

• Requires a Bluetooth LE chest strap, chest band, or external HR sensor (Heart Rate Service UUID 0x180D)
• Built for BLE heart rate belts and generic HRM chest straps
• Auto-reconnect to your last strap or band
• Background recording with the screen locked and a persistent session notification

LONG-TERM RECORDING FROM YOUR STRAP

• Record heart rate for hours during extended sessions
• Live BPM charts plus RR / HRV when the strap sends beat-to-beat intervals
• Min / avg / max, session events and notes
• Notifications for high/low HR, strap disconnect, missing data, low phone battery

HRV TRACKER & FITNESS ANALYSIS

• HRV metrics: RMSSD, SDNN, pNN50, Poincaré plot, RR histogram
• Structured fitness tests with recovery tracking
• History with connection gaps — see when the strap signal dropped
• Optional session export for spreadsheets or sharing with your doctor

COMPATIBLE CHEST STRAPS AND BANDS (BLE)

Works with Bluetooth Low Energy heart rate chest straps and HRM belts that expose the standard Heart Rate Service, for example:

• Polar H10 / Polar H9
• Wahoo TICKR / TRACKR
• Garmin HRM-Pro / Dual (BLE mode)
• CooSpo / Coospo HW807 / H808S
• Magene H603 and similar Magene BLE straps
• ThinkRider and other generic BLE HR chest bands

Heart Control is an independent app and is not affiliated with sensor manufacturers. If your strap or band appears in a BLE scan and offers Heart Rate Service, you can connect it. Moisten the electrodes, wear the belt snugly, and keep the phone nearby. Some sensors send BPM only; others also send RR for full HRV.
