I absolutely love it! You can pinch-to-zoom anywhere on graph, and scroll left/right. Likewise; you can scroll thru 'data list', a red box moves within graph, to show where data reflects in graph. There's also a green vertical bar that makes it very easy to see when charging started & stopped, and shows exact date & time.

I don't know what's happened to this app, but literally all it's doing now is displaying full screen ads, making it completely unusable. Every time I close the ad, another one (or often the same one again) appears after literally 1 second or less, so I can't do anything at all! Edit: Given a star back because I've finally found a way to make it work for now - turn on Flight Mode. Edit 2: Seems fixed now, ad just shows once on opening app

This has been my go-to battery health and monitoring app for many years but then they introduced full screen ads, and that's the line that shall not be crossed. Adding to the constant issues with the app service being slept and it missing data these days means it's nowhere near as useful as it used to be.
