    Christian Sarne


    Three Things: 1. It only does clean the cache and stop some apps, where the system apps does that. 2. It don't fix any Bugs or Lags even if you have excellent signal in the game. It does eat the memory. 3. For a free version, it should do what it say and not in the premuim one. The premium version should only have the extra features not the core feature. and change it's name to cache cleaner it do well in that regard.

    despite most of the recent phones have built in game launcher but old ones (not even flagships) don't have them. and there are no other game launcher app in the store. so its a unique app with great potential. but i have no idea it does help or not. need a lot of working in the app and OMG to much add.

  3. The T-Man Show-avatar

    it does NOTHING! its just like the kther falsly advertised 900 other apps... its just an app the that made to look like its clearing random stuff, but its nit, thats what thebapp is made to ro, "look like its cleaning". nithing speeds up or is smoother. NOTHING! dont waste your time with this app! so called "creater" doesnt reply or take the app seriously, so dont give him your BUISNESS since he wont make a application thats actually going to speed your ram and system up! i hate liars and users
