How to choose

  • Accuracy. Look for apps that use both the camera and flash for photoplethysmography, as this method is more reliable than using only the camera. User reviews often mention if readings match a chest strap or manual pulse check.
  • Battery Usage. Apps that continuously monitor heart rate can drain your phone battery quickly. Check reviews for feedback on battery impact, and consider apps that allow selective background tracking.
  • Data Integration. If you use other fitness platforms like Apple Health or Google Fit, ensure the app syncs seamlessly. This allows you to see all your health metrics in one place.
  • Features vs. Simplicity. Decide whether you need advanced analytics like HRV and stress scores or just a simple bpm checker. More features often come with a steeper learning curve.
  • Cost Structure. Some apps offer a one-time purchase, while others require a subscription. Determine your budget and whether the free version meets your needs before committing.
