This may be a long story, but I’ll try to keep it short. I’ve had rhythm issues for a long time, and was always brushed off due to my age (started at 17, I’m now 37). Over those years, I fought to be heard and treated, since my family history holds a strong line of suspected sick sinus syndrome, afib, and valve disorders. Recently I tried a new cardiologist who advised me to invest in an at home wearable in order to catch my issues to send over to him, being pauses are very hard to find from a medical standpoint without some added help. After much research, I landed on the H10 due to its constant ecg capabilities. I ordered and when it arrived, I downloaded your app, put it on, and within the first four hours I caught a 5.2 second pause that I confirmed with Qaly, an ecg interpretation platform filled with cardiac telemetry specialists. A few days later, I lost consciousness briefly and caught an 8 second pause. This data was sent directly to my cardiologist, who was not only able to confirm my sinus arrest, but rush order a loop recorder implantation for me. I’m now awaiting reports to come back from my doctors office via this loop recorder in order to be fitted for a permanent pacemaker. I just wanted to say thank you. Even if we aren’t finished with the journey here, you basically saved my life. I’d give you a 50 star if I could.

I bought the Polar H10 for a AI project I’m working on. I had congestive heart failure 2 years ago and try to combine cpap data, personal measurements, and HRV data, to try and heal my heart. After getting the H10 I was VERY disappointed in what was available to record, save, and down load, the data for my use. Every other app made their app so complicated with all the algorithms and sports suggestions that made the H10 useless to me. The AI suggested that I look at ECG Logger and I must admit I am blown away by what it can do. Not only is it simple and easy to use it does one thing and does it great! It records H10 data and emails it! The app doesn’t shut down or loses everything when I leave the Bluetooth range. It just marks time until I move back into range. ECG Logger puts all the H10 data into a CSV file that it emails to my computer. My AI said “this is the best data of all the H10 apps you sent me”. It has raw ECG, RR intervals, heart rate, accurate timestamp, graceful handling of Bluetooth loss, no proprietary calculations, in a simple CSV format. I couldn’t’ ask for anything better!

This app is absolutely brilliant. It works perfectly and is exactly what I needed. There is nothing else like it in the App Store. It continuously (and reliably) records my heart data for as many hours as I need, and hasn’t had any glitches yet. I also love that I can save my files in .csv format or export them as .pdf files. I had an issue when I initially downloaded the app, and the app developer replied to me within five minutes after I emailed him a few days ago. He was extremely helpful and very kind as well. This app is wonderful and is a great deal as well. Thank you!!! I would leave ten stars if I could.

My experience is the app works perfectly. The app’s user interface is very nice. The paid version will allow you to download hours of 130 Hz ECG data in .CSV format that you can analyze to your heart’s content. The author was very responsive to my questions. If he writes a new version that lets me get the accelerometer data too, I’ll get it,
