5 stars: LOVE this app. I wanted a way to measure battery capacities. Found out batteries had less than half the capacity of the 3220 mah it should come with, even the supposed \
4 stars: Lots of fun to explore and gives useful insights into power consumption and charging characteristics. Would be nice to have uploadable CVS info for Excel statistical analysis. Better yet would be an ability to sort, filter \u0026 graph parameters of interest right within the app. The App may offers those features now, I'm still getting familiar with the App's capabilities.
4 stars: Needs Improvement. I paid for the Pro, well worth it. It's great. I get it on more than one device too, including my Samsung Tab A w/Marshmallow 7. But it sucks it's not compatible with my Galaxy S4 w/Lollipop 5.0 where it is needed the most, not even the free version. On my main device, Pixel XL with 10, it works perfectly, 5 stars for that phone.
5 stars: I like that it gives you the milliamps and voltage supply realtime when charging. I have a OnePlus and wasn't sure that a LG fast charger I was using wasn't over voltage for my battery (max 9v output 1.8amp) when charging. Thanks to the app I now know it's fine and well in range of running on the minimum 5v 1.8amp. I like to slow charge my phone's to prolong the battery as it builds up less heat.
4 stars: The latest update failed to start after rebooting the phone which made me miss the battery charge alarm. Weird. This had never happened before...
