After testing this app on two devices (SM-T111 & SM-T350, described above), I can say that overall I love this app. It's a convenient way to get a lot of info in one place.
I compared the numbers side by side with the 3C pro app and most were within range of each other with the following exceptions:
App reports the 350 isn't rooted. It is, w twrp, su & busybox installed.
Cpu load differed significantly with 3Cs numbers on both devices.
Cpu temp on 111 reports as 80000 deg C (actual # is 80 deg, prob just a missing decimal.
Other that I will highly recommend it and have already given it 5 stars on Playstore
Thanks for your feedbacks.
I fixed the CPU Temperature bug that affected some devices.
For the other problem, I'm working on.
