I use this app as a track of my heart as I have an undiagnosed heart condition,I tried premium for a trial and I didn’t see the point in paying the price only because I don’t believe the information it tells me is true, but it’s okay to check your heart rate every now and then. I believe it could have more options in part of the free tracking and that may get more people to buy the premium.
please don’t rely on a fake app for your health. you can buy cheap heart rate devices on amazon that are accurate. this app is designed to scare you with “abnormal result” so you pay for premium. i did the test as it said it gave different results to my accurate hr device and i place it on a pink towel and it said my towel had a 100bpm heart rate.
Great Product very accurate.
Very bad , don’t buy , some how thy took my money out my bank account but I did not subscribe to this app only downloaded it to see what it was like asked for a refund. Never got it back 29.99 very on Apple in total cost me £36.99
This App is completely fake, the developers are trying to trick you. The only thing this app does it turn on your flashlight. I put the “sensor” which is actually my camera on a blanket and it read a heart rate of 78. Uninstall this app as it is a waste of storage
