Firstly - this is the only sensible app that I have ever tried for AFIB detection. There is no other like it … and it deserves big credit for that, and more people should know. But while I have used this app for several years and found it very helpful - both in the clear information it provides, and for the measurements it achieves, I just found that the latest version is not better, and has a loss of good features: 1. The calculation basis is no longer visible, so there is no longer summary values. This information used to provide a good basis for understanding reliability and accuracy being achieved. 2. The colors used now make the results harder to read. If you click on an entry in the history you get to see slightly more info - possibly the colors being used are hiding this info. 3. I was very happy to pay for the full version, but discovered that this was nothing more than being ad-free. Improvements needed: a) return all the statistical data (even if that was by clicking a button to show info) b) fix the colors to be more readable, and to reveal all info c) make it possible to share the results in non-Facebook tools (eg. email or other messaging tools) Please do keep improving this tool… there is none other like it on the market. And thank you !
