Awesome ECG, accelerometer and RR intervals logger for the Polar H10 sensor! It works amazingly well, and continues to work even when the screen is turned off (despite my phone being stringent on energy saving and usually closing everything it can, even instant messengers!). All the data is saved in realtime during the acquisition in separate CSV files with timestamps both in the filename and per row, and are stored in a sensorDataLog folder at the root of internal memory, hence even if the acquisition is prematurely stopped or the phone shuts down during the acquisition, the data is not lost. It only needs Bluetooth, so I could activate Plane mode and disable Localization to save on battery, after 1h30 of acquisition of both ECG and accelerometer it only used 1% of battery! There is just one thing that could make this app better: why not make it open source??? It's clearly geared towards research, it would be a very welcome addition to open the source to all researchers!

The heart rate graph still crunches up instead of leaving the graph but otherwise the app has regained my confidence.
★☆☆☆☆Mark Raymond· Sep 13, 2021
Even though my Polar HRM and my phone were the only devices within Bluetooth range of me, the app refused to connect to the HRM, stating it was connected to another device. I had previously connected to my treadmill, but that was turned off at the time. And 40-50 m away... uninstalled.

Good when it works but crashes quite alot

Doesn't work at all. Connects to sensor but just says "HR: waiting"
★☆☆☆☆Clive. Winfield· Jan 31, 2022
This app is constantly letting me down now. As with polar flow it is a massive disappointment to use, always losing vital data. I monitor my heart rate 24 hours and can't afford to lose that data. This is a massive blow because polars hardware is second to none, but what a waste of technology. I've now ordered a Forth Frontier. Time to relax at last! Ps this app is not" easy" to use I'm" sure" Reinstalled again. I have several polar devices and this app fails with them all.

In theory this is a great idea, but it doesn't show graphs and the app os hard to use.
