EG4

This app works one time and the next day I need to restart my phone to get it to work. Not easy to deal with

This eg4 utility is better than I expected. It’s as good as the SOK-BMS app that I use on those batteries. This doesn’t tell you the charge cycle count or the balance state but the latter at least is available in their windows tools. I like it. The only con is they could have packed every thing into one screen instead two. Well another is you have to choose the bluetooth device every time you start the app and there’s no apparent way to save that info once so you don’t have to enter it again. BTW it looks totally different than the images shown in the listing here, much more attractive.
