ECG Viewer & Recorder

Good start, but to be useful it's missing a few things. It should display on standard ECG graph paper and at the proper scale. Without that it can't be used to inspect rhythms since it's impossible to judge the distance between the P wave, QRS complex and T wave. It should also record heartbeat. Also should be able to add notes of what activity was occurring, eg, running, and have those notes in the file. Should be able to record a whole day. Good start but missing some key features

This app exemplifies the brilliance that exists in the basics. It's name tells you everything you need to know and performs exactly as advertised. I recently requested a new feature (output file storage selection). Matti quickly responded and implemented the request in a timely manner.

Would be a great app if it worked. Instead it loops on inputting your Polar H-10 ID. It appears to take it, but as soon as you try to use it it asks for it again. I have put the ID back in enough times so I have memorized it, so the effort wasn't a total loss

This app does exactly what it claims and does it well. The detail is amazing to me, and the app is easy to use. It paired easily to my polar H10. What's more there don't even appear to be ads at this time. Just today I asked the developer to add a heart rate number to make the app more useful while exercising. It seems like all the hard work has already been done.

Amazing, wish I found this sooner! Thank you so much for creating this app, I've just splashed out on an ECG enabled watch then was disappointed to find out that it doesn't work properly for fast heart rates.. forgetting I had a polar H10 I went on the hunt for something that worked with it and stumbled across this. Thankyou, please keep it live, I'd gladly donate to help it keep running!! Really clear, simple to use, worked seemlessly. Addition of heart rate would top it off. Thank you!

Would give the app 5 stars if it could simply print to pdf the graphic visualization of the EGC. Thanks in advance for putting in the effort to do so.

While this isn't particularly useful for reading or displaying an ECG for medical purposes, it does allow the user to record ECG data from a Polar H10 device just as the SDK provides it. That happens to be just what I want.

Works ok but won't record, which is what I wanted this for. Keeps crashing Update: update fixed this, works well, thank you!

Awesome app Feature request: 1 It' very easy to inadvertently exit the app, please allow Exit only with a menu command. 2 Screen capture when artifact detected.

Doesn't seem to work. I setup with Polar Best first, gave this app all permissions, enter the ID, and nothing. Another some lar app does shoe the ECG tho. Hmmmm, I really want this one to work.

Connected to my device but unable to get a readout. I installed and reinstalled twice before my final uninstallation of app.

Could you add the option to keep the screen on? Otherwise fantastic apps.

UPDATE: all issues regarding data files now resolved. Excellent app.

Only works occasionally. Alot of recorded files fail to open

Working as described. Pretty basic tool but can be useful.

Any chance to open this up to Garmin Chest straps? Love this as an afib sufferer, not sure I want to throw away a new strap to get a new strap

Working great on Android 11 with polar h10 thanks.

Anything this hard to use can't be the best idea.

Great app, simple to use, exactly what I needed.

i have polar h10 versio 3.1.1 and it only shows heart rate and not a cardiogram.
