Shows my Snapdragon 810 incorrectly as being 4 x A57 at 1.57Ghz and 4 x A53 at 2.0 Ghz, instead of the other way round. No Idea Why! Would probably rate it as 4 stars if not for this, as what else is it getting wrong?

V70%
by V####:

Love it, it told me what I really wanted to know, which is how much percentage of time my processor actually spends doing what it does. Turns out it maxes out seldomly, which is good, and explains my great battery life. Android 6.0 on my Moto X at least is excellent at going into CPU sleep mode, and this app helps me see what it's been doing.

by C####:

Nice adjunct to another app i've been using for a long time and on, now, 3 platforms. Actually gives real time CPU operating performance, unlike other tests. But last test caused overheating and the battery is 5000 not 1000 ma.
