So fast, easy, and free, what a great gift for all android users. Free with Ad yet complete full version to use, a trend that many should follow without bloated inapps yet they come with sluggish performace. Love it. One of the hidden jem and so proud to have it. Developers go ahead add Donate button somewhere. Install it, you will be amazed.

I was a bit dubious at first; I was installing this app to free up space and it in itself takes up a bit of storage - but it was well worth it. My phone started working faster, I was able to download apps when before I didn't have enough space. The cooling feature is great, too. I would have given it 5 stars if it wasn't so pushy with using all the features (charge booster). Other than that I can't fault it. Great app.

I loved clean master especially for the game boost feature. The last update made game boost much much slower and also 70% of the apps in the game boost are now hidden under large and very annoying ads. Long story short its slow, unwieldy and doesn't speed things up anymore. Awful update don't waste your time with this app anymore

B70%
by B####:

I still haven't recovered from you messing up the move app feature. Now you've messed up the game launch folder feature. Good thing the basic function of cleaning and boosting the phone still seems to work. I'm losing faith in this app.

O70%
by O####:

It really helps to boost my phone. However, the "game folder" feature now is no longer a folder. Why does it open the app when I tap it? Please revert back to folder view and show all games when opening, not just 6 "most used" ones (I feel like it doesn't have any specific order and for some reason it cannot be reordered).

I am changing my rating from 4 to 2 since the new update the game boost option is now terrible you cant move your game in the order you want them anymore they are now all added alphabetically, you also cant uninstall from there anymore and when you open the game boost it now only show the first 3 or 4 games not all the games you now have to select see more will change my rating again if these things are added back to this app Thanks for the update but still not fixed and now it is even worst because now the app doesnt even turn to landscape, and i have a tab and it use to work just fine till the previous update. All good and well to want to make it better but why change the thing that is good and everybody enjoys

Just installed Update Thurs 25 Jan. GAMES BOOST FOLDER PROBLEM IS STILL NOT PROPERLY FIXED DESPITE CM PROMISES. Slight improvement in that icons are back in similar order to what I had but I still can't move them to reorder if I want. WHEN WILL IT BE FIXED PROPERLY SO IT FUNCTIONS LIKE IT USED TO? THERE IS ALSO A BIG ADVERT PROBLEM NOW, AFTER I USE ANY CM FEATURE I NOW GET 2 ADVERTS TO CLEAR NOT JUST 1 AND IT'S OFTEN 3 WHICH IS GETTING MORE AND MORE. RIDICULOUS. IT IS MAKING APP ALMOST UNUSABLE FOR ME. LIKE MOST USERS, I HATE HAVING TO TAP MANY TIMES UNNECESSARILY TO DO WHAT I WANT AND CLEAN MASTER NOW REQUIRES SO MANY TAPS TO CLEAR THE RUBBISH IT'S MAKING US USERS WADE THROUGH. I AM READY TO UNINSTALL AFTER MANY YEARS LOYALTY. Update 18 January 2018 has wrecked Games Master Feature for me. I had previously sorted my games within the games boost folder so that the ones I play most were at the top and in the order I wanted. I could, therefore, see my favourite games easily and play them and not lose daily bonuses by forgetting to play. Now the order has been changed and I can't even move the games around in the folder to restore the order I want. (Previous updates annoyingly changed my order but I was able to move icons in the games folder to get things back to how I wanted.) As I can't even do that this time, I now have to search through to find my favourite games which is time consuming. Also when I try to exit games folder, it takes me through the Clean Master main screen rather than directly exiting like before. This takes even more time and ruins the feature even more. Please fix the problems. Looks like other reviewers also have a problem with what you have done. I HATE UPDATES THAT RUIN THE THINGS THAT WERE WORKING FOR ME.
