Nox has always been my go to, it works is why on free. The pay version also is affordable, there's a yearly option, and they have added earning rewards to both that are outstanding. So I have never strayed, always coming back because we all know when a app like this isn't working and do not forget the ads every 5 seconds. Nox is legitate and they do care about their customers.

Impressive: even with the ads... i run and test many an optimizer app: this one has a clean interface (easy to use on android phones), it found an old apk (install file) that i did not need, it has a free virus scanner (that is reassuring). the scan is fast, even on my old HTC One M8 (a fast phone for its time, but slow by todays standards). if devs removed the clunky ads , this would be a perfect optimizer. maybe they do in the paid version?
