"body": "I like the data this app shows. I can feel extra “bumps” or larger bumps in my heart beat which is why I got the Polar but I wanted the ability to observe and record. i will have to play around with the raw data but should be easy enough to import into spreadsheet. but I think I might see if I can build some Java app or something to chart this data. Been a long time since I did any programming. I did purchase the subscription, the developer’s idea was sound on implementing this instead of outright purchase an unknown app. Cardiologist here in S. Korea didn’t see any issues and said nothing to worry about but these bigger beats are frequent and doesn’t seem right. Recording data while I’m still here, especially at night when it seems the worst (probably after being exposed to air pollution all day). Mornings are pretty calm and it could be that I am running two air filters in the house. Who knows without the data. NOTES TO DEVELOPER Initially had issues connecting. Don’t know what was going on. Open up app for the first time and got “would like to use BT” (allowed), then pairing request - allow, then tap on Connect, tap on Polar H10 serialnumber but nothing happened. closed app and opened another app Elite HRV and ran a test. Closed that out and reopened ECGRecorder and tapping the H10 still didn’t do anything. Since not connecting I deleted app. But, Developer response was super fast so I downloaded again to screen record. Now, this app connects to my polar H10. So I don’t know what was going on because I went through several steps like cycling BT off-on and connecting the Polar with other apps and force closing those apps before retrying with ECG Recorder.",

"body": "Purchased a Polar H10 after reading study after study where they are used to record ECGs. Immediately realized that neither Polar nor Apple support monitoring/recording of the ECG data that is output from the H10. Spent days looking for something like this app, and then there it was! It’s does exactly what you’d want: it displays and/or records ECG output. It’s a great app, and the developer is quick to respond to questions or feedback. I wish everything worked this way!",

When I opened it on my iPad, I was asked to pay again. Should this app work on both my iPhone and iPad which are on the same iCloud account? Thanks for offering such a useful app.",

"body": "Works exceedingly well for monitoring my exercises (rowing machine, hiking, and walking). An unexpected benefit was its invaluable help in diagnosing the heart rate subtleties (via the 'R-R Interval' and 'ECG Stream') associated with my nighttime sleep issues. Live plotting on the iPhone, along with data exporting to plotting software (spreadsheets, custom computer programming) makes this an invaluable tool.",
