Ever since I have installed this app, it has increased the life of all my smartphones. it keeps my phone clean, up and running all the time. It also helps me save battery life and also in the last minutes before the battery dies. I would recommend this app to everyone. sometimes it forces you to use the app in between, and it's okay with me as it's for my own good. keep Smiling and loving.

- LNiiharika Shankkhwar

So far so good, the app is keeping my phone clean and my phone is running better. My phone was very sluggish prior to putting the app in. There are some ads as it is a free app, but I find they are not too obtrusive and once in a while I watch the ad so Clean Master can benefit as well. Overall it was a good decision to use this app.
