Apple Health Verbindung wäre geil
Best Polar H10 app on the market
Trying to Charge me double after LIFETIME membership.
Response from developer
Hello, the purchases are handled by the Apple App Store, not by the app. Does it work in the meantime? Feel free to contact support at ecg-recorder@poeml.de
Not working and limited documentation
Funktioniert!
Leider hätte ich noch gerne den Beschleunigungssensor des H10 ausgelesen, um auch Schlafanalysen zu machen. Vielleicht kommt das noch in Zukunft, um den fünften Stern vergeben zu können.
Thank You!
Subscription
Response from developer
Hi. Glad that the app has been helpful. You can cancel the subscription in the settings of your Apple ID. See here for help: https://support.apple.com/en-us/HT202039. Please consider to revise the 2-star rating. Thanks!
Does exactly what it says
Works perfectly with H10.
If it automatically worked out the HRV from the r values, I wouldn’t need anything else!
Works well but can’t seem to record ECG more than 2 hours
RR intervals and HR record for extended period (>5 hours) with no issues.
Response from developer
Hi and thanks for the review. Can you contact support at ecg-recorder@poeml.de to solve your issues? It is a bit strange, because since version 1.3 or so ECG data gets autosaved in case of a disconnect of the H10. Also, with my H10 I was able to record over night, more thatn 12 hours. Maybe we can also find out what is disconecting, the H10, or the receiving device. Thanks.
Disappointed- not connecting
Response from developer
Hi, thanks for your review. Could you please contact support at ecg-recorder@poeml.de? I am sure we can figure out the problem. Are you able to connect to the H10 using the Polar Beat app?
Forced payment
Response from developer
Sorry, not everything that's on the internet is free... :-) But you are welcome to use the free trial mode. No popups there and you can test if you like and/or need the app at all. And if not, no need to buy. And no need to leave a bad review. Thanks! Added response: Thank you for the "garbage" and the "lazy nerd" that is very useful feedback! And if you were looking closely, you would see that the app is not collecting any data at all, so (unfortunately) nothing to sell. Enjoy!
Works as Described
Doesn’t connect… I fixed it
Great idea but it doesn’t work. Bluetooth is on, the Polar H10 is available and visible in the app, but after I click connect, nothing happens.
Response from developer
Hi, glad you figured it out. Yes, the H10 needs to be "free", i.e. not connected already, otherwise it will not accept another connection.
Great app!
However, I purchased this app on my iPhone. 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.
Response from developer
Hi, tanks for the review. Yes, it should work on multiple devices without paying more than once. Are you sure you installed both times with the same Apple ID? Please contact support at ecg-recorder@poeml.de Thanks!
Add time stamp please
Can you add time stamp to app?

Hi, thanks for reaching out! Can you explain what time stamps you exactly mean? Feel free to contact me via email.
Revising 1-Star
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.
Response from developer
Hi, glad to hear it is working now. And thanks for describing the problem. I do not know yet what could have gone wrong. But often deleting an app and installing it a second time it might start working. Please have a look at EDFbrowser and the demo video for it on the app's github page. Maybe this is what you are looking for. I will update the help section at some point. Thanks again for your feedback! An please don't hesitate to contact me via email.
Not sure how this works
Response from developer
Thanks for your review. I invite you to have a look at the help screen where it is explained how it works with numbers and excel. Also, have a look at the demo videos on the app's github page. And please contact me directly for further questions. Thank you.
