5/5Crystal Clear
Love the insight into the operation of my phone. It’s good to know what my processor is struggling with and what’s eating up my RAM. I wish I could use it as an overlay in my apps to see in real time what’s happening. Like PIP window in the corner. But honestly this is a great app. It gives me insight to how my phone is running.

2/5You cannot find one single word about what you get on the pro version
I dont get it. Its a nice free app and i use it to free some space on my ipad Ram. But it never stay for long , i tried to get some info of where all my Ram is working but you cannot get much info but title on where it used. I thought maybe the Pro version will give me some more info or option to fix things , but nothing , not on the app any not on the app store download page Shame
