Kardiograph Klassik

Reads 20-30 higher heart rate than actual. Used BP Cuff to get actual heart rate. Not worth the 99cent I paid.

Very good

This App worked very easy on pre-iPhone 13. I was stumped at first and then found the App works very well with one of the new photo lenses. You will have to move your finger around until you find the correct lens.

It’s what I need!

Really hate the flat design. This skeuomorphic design is outstanding, keep it alive!

This doesn’t work. I paid for it and it never has worked consistently. When you pay for something, I expect it to work !

App will only record a regular rhythm. This is not beneficial if trying to document issues to show your physician. Only gives you a 0 for rate and no rhythm strip. Needs button to allow you to accept strip if not perfect regular heart rate.

Pulse number is probably correct but the waveform is a phony animation lol that has nothing to do with the camera’s flash whereas cardiio waveform actually relates to changes in blood flow.

It works!!!

I lord this and it worked for literally four days. Them suddenly no matter what I do it doesn’t seem to work. Bummer
