How does it work?
Optical heart rate monitors use light to track your blood. By illuminating your capillaries in your finger-tip with a light source (Flash), a sensor (Camera) adjacent to the light measures the frequency (Heart Rate in beats per minute [bpm]) at which your blood pumps from the "redness" of the images it captures.
What is the best way to measure?
Cover the both the flash and the camera with your finger. Apply a steady, light pressure. A great way to do this is by resting the phone on your finger and let the weight of the phone do the work. Keeping still while the measurement is made also helps. For example, it is best to not talk while making a measurement. If you are having trouble getting a steady signal, you may find using a different finger helps.
How accurate are the measurements?
Heart Rate Touch uses sophisticated methods to keep measurements accurate. Under ideal conditions, with constant pressure and minimal user movement, measurements are accurate to within one beat per minute (bpm). Your results may vary.
Can I export to the Apple Health app?
The first time you make a measurement, you will be asked if you would like to export measurements.
Can I export my information to other apps?
Yes. Go to "History" and then tap on the 'Share' button. You can share your measurements with Mail, Airdrop, or even other apps such as Apple's Numbers.
Can I delete a measurement?
