I have used this app for years and bought the pro version to monitor my battery properly, ever since oem phone makers went to non removable batteries. Unfortunately, I think recent updates to Android prevent the app alarms from working properly. Only one alarm sound can be set for the app, no matter what it is being applied for. That was my favorite function because I could set different sounds to know when the battery hit specific moments in charge status.

I downloaded GSam to pinpoint a rogue app that was running and draining my battery. My s8+ didn't even last 8 hours before dieing. After using it's instructions to install ADB on my computer and grant it additional access for information I was able to find the app constantly running. It was a Samsung app (find my mobile). Using ADB again, I was able to uninstall it and now my battery life is improved significantly. Back to the way it was when I first got my phone. Not only did this solve my problem, but it taught me a little more about the Android operating system. Had to buy the pro version of the app right then and there out of respect for you fellas. Great work!

This is a very compact, yet information-filled application. Installed it yesterday onto both a Note 4 and a Note 9, and all is functioning okay. I appreciated the information provided to allow the ADB adjustment, giving the app better access to information within the Android OS. There is some customisation to the interface colour, notification and widget icons. A small improvement could be to use RGB values instead of a fixed pallet to allow a better selection of colour choices. One other thing that might be nice to see in a future update, which I haven't found yet, is a little addition to the page showing the application stats, whereby the values are updated every 'n' seconds to show a closer to real-time view of application process/battery usage (really useful for determining what processes might be running hot at a given moment). All in all, a great app that works as advertised, is very well-put together in a compact, sleek interface, and will undoubtedly help solve a few future battery/cpu issues down the track. Nice job...
