Frequently asked questions
Can heart rate monitor apps work without a wearable device?
Yes, some apps like Heart Rate Plus use the phone's camera and flash to measure pulse by detecting color changes in your fingertip. However, this method is less accurate during exercise and only provides spot checks, not continuous monitoring.
Which app is most accurate for heart rate tracking?

Can I use a heart rate app for treadmill running?
Yes, you can use heart rate apps during treadmill running. Apps like Polar Beat or Wahoo Fitness work with chest straps, and you can mount your phone on the treadmill to see real-time data. Optical sensor apps may be less accurate due to movement.
