5.0 out of 5 stars Really well designed and effective 2 Feb 2014
By jim
Verified Purchase
Im using this in conjunction with the 'ES3' group and Malwarebytes, and they all work together without any conflict, and give me total control over what runs, what gets installed and what gets deleted on my Kindle Fire. (Control that Amazon deemed us unworthy of, but thankfully we can retake control of the device with apps like this))

I didnt even think about security on the Fire for a long time, until it became more than just an e-reader, and I started using it for more day to day tasks that I would normally do on a desktop PC (such as shopping etc).

Now I use and try out many more apps, and most of them will leave a footprint of some kind after they have been removed, or keep some function running all the time without you knowing...this app is perfect for quickly killing anything that is running (Be Warned this includes applications and files that you might want to KEEP! If you cluelessly mash buttons on this program, you may even kill or remove CRITICAL system files..this is what happened to the 'one star' reviewers who claim 'this app ruined my day'....its impossible that the app did what they say of its own accord : D)

I use this to kill processes before Im going to use an app, just to keep things smooth, and it works perfectly..I use ES3 to identify errant files, malwarebytes to find the unwanted processes, and this app to deal with them.

Even if you dont want to do all that, this app is a must have really on its own, to keep your device running silky smooth.

Im sure anyone who has had an android device of any flavour, has noticed it getting a bit jerky and slow over time, especially if you add and remove a lot of apps, and move, copy and write a lot of files...this app will keep all that nice and tidy.

5.0 out of 5 stars clean master 23 Dec 2013
Verified Purchase
My kindle fire hd had got very sluggish and very short on space with only 1.8 gb left. After using Clean Master it very quickly cleaned up and gained another 1.8gb. Excellent product and very easy to use as long as you are careful what to delete or clean. If you're not sure do a few test runs with stuff you don't need.
