### 2/5 — Unusable

*2022-02-03*

The app UI is so basic that I couldn't tell what's going on or work out how to use it.  I've followed the instructions that came with the Battery Guard device and hit the Scan button to find the device but nothing happens unless I kill the app and restart it. After pressing scan do I press the Connect button after selecting the found charger device? I did so but apparently nothing happens. So I press the Save and Continue button and up pops a dialog to set the time, but what time? When charging starts? Or finishes? There's no indication of that until after setting the time. So I've chosen the time but after that there's no indication of charge progress, and the chosen time comes and goes and still there's no indication of what's happened or what's going on. 
I'm starting to think the Battery Guard is pointless, with the way the app works right now, I've no idea I'd it actually does anything.
