The free Instant Heart Rate app uses the existing camera technology on your Android phone to measure your current heart rate. Simply open the app and place your finger carefully over the camera lens, making sure not to press too hard and to apply consistent, yet gentle, pressure. Within 10 seconds, the app measures your heart rate, and outputs the number on the screen.
The app creator touts that the technology works based on color changes in your skin as oxygen pumps through your finger with every heart beat, and the light from the camera measures those changes to calculate your current heart rate.
It is a clever and impressive way to utilize camera technology to bring another use to your Android phone, and it’s free!
Avid exercisers will love this app for measuring their heart rate on the go, making it that much easier to ensure they hit their target heart rate. Hitting your target heart rate during exercise increases your metabolic burn. Who knew your Android phone’s camera lens could help you lose weight?
Non-exercisers will love this Android app for its show-off capabilities. You might not think you want to measure your heart rate with your phone, but believe us, you do!
