Use it for calculating heart rate
While we all know that smartwatches like Apple Watch can be used for detecting your heart rate, did you know that you can do the same using just your iPhone?
Install the Instant Heart Rate: HR Monitor app from the App Store on your iPhone. This app can be used to almost instantly calculate your heart rate by monitoring your pulse.
All you need to do is place your index finger on the top of your iPhone’s camera or the flashlight. After a few seconds, the app will accurately calculate and show your heart rate.
I also used my Apple Watch to calculate my heart rate to compare the results with the app, and they were surprisingly similar.
