Real-time heart rate alerts when you need them most. Connect any Bluetooth monitor and get instant sound, vibration, or notification alerts. Your heart health, protected.

VERSION 2.4 - COMPLETELY REBUILT FROM THE GROUND UP

Everything that was premium is now FREE.

HeartSafeAlerts 2.4 is a complete reimagining of heart rate monitoring on iPhone. We tore down the old app and rebuilt it with one mission: make professional-grade heart monitoring accessible to everyone who needs it.

No subscriptions. No paywalls. No limits. Just powerful, reliable heart rate monitoring - completely free.

THE FREE REVOLUTION
