1. Took a little figuring out due to having a wide angle lens between my main shooter and the led flash, but once I worked out the kinks, it does its job well.Unfortunately wildly inaccurate, consistently returning results 30bpm higher than a couple of other apps I tested.
2. Galaxy note 9Don't bother with this app, I had the camera and light pointed up in the air and it was reading a heart beat............This is a wonderful app and it works very well and tells the right heartbeat rate and I'm satisfie with this app, so thanks developer.Love the simplicity of it all.
3. don't waste your time with it.There is still a difference in the reading compared to the doctor's equipment by about a 2 to 6 point range either way.Very good and stable pulse measurement.
4. A share option and auto send to other apps like fit from Google would make the app better.
5. dobt know how the app knew that since this measurement was taken with my phone face down on the floor without me even touching it.
6. Tags are nice, but there's no filtre for measurements of each tag.Simple and fairly easy to use.
7. Perfect for someone who doesn't want to deal with all the download stuff.
8. Maybe it's just no good on the Pixel 2?I decided to do some experimenting.
9. apparently my heart rate was 110bpm.
10. Keep default setting.not sure about the accuracy.
11. that flash gets hot, and this app burned my finger.
