The reason for not extending the update is that this program is good

For cleaning junk and freeing up memory, UC cleaner is the best (based on size) for this. But, please update the app to clean deeper coz it doesn't completely stop any apps even if not currently used and always have to stop them from device settings, especially facebook and messenger that use high RAM.

I have used many cleaners like clean master, 360 security. Problems with them is they are not complete package. Always suggest something more to download. And of course, ads are to pop up every second. But Ucleaner is ad free. Complete package. Its layout is amazingly beautiful. Highly satisfied.

Finally found the one utility app for clean up, etc for my tablet and cell. Non intrusive and does what I need. Be gone CM products. When we are all new with android stuff and eager I see quite a few of us fall in to the CM trap, then we wise up to the shenanigans. Great app.

Perfect app, works as expected. For all the cleaning app I have ever tried, it's only this UC Cleaner (Boast & Clean) that is able to Boast my device. It's force-stop all the apps that run on the background when you click on Boast; this action prolong your battery, and also keep your data for only the app you desire to open, making your browsing faster and smother compare to when every other app is taking part of your data on the background.

This was just what I have been searching for wow uc dev first your #1 browser and now this awesome cleaner that really save my phone from run like turtle and speeding like racing car. It memory booster is just amazing along with file cleaner and boost box's is the best got all my apps run fast by it.

When I touch the Icon, after I have downloaded it, and then try to open it, nothing happens. I uninstalled and reinstalled and it still did not work

Kus. D. C. Sep 3, 2016     

1- Like any other cleaner it cannot free much ram, just around 200mb,coz mine is a xiaomi phone..though I even tried giving accessibility permission. Though I think it's tagged under xiaomi cleaner....* 2 - in notification toggle flashlight & camera doesn’t work. Flash doesn't get started & camera opens in ten sec that too with a black screen..... * 3 - And does this clean automatically or not? It would have been great if we could tell it to auto clean when ram is under 550 mb otherwise xiaomi has cleaner

SID. M. Nov 23, 2015     

It's all fine on my SAMSUNG GALAXY GRAND PRIME SM-530H but in notification widget FLASHLIGHT 🔦 not working. When I click it it automatically switches OFF. So I rated 4 / 5 otherwise it's a 5 definitely.

Nar. G. Sep 18, 2015     

I have recently changed my sd card from 4gb to 16gb but app is showing sd card space 4.82gb instead of 14.82gb. I reinstalled it but problem persists.

Cool, effective and lite app for hibernating uc browser. It works well with greenify (greenify marks uc browser as perceptive so it cannot disable it) . Although i dont like the sticky message, please change it and make it more useful and more awesome design.

Tin. N. B. Aug 27, 2015     

Since this last update, my floating widget won't stay on my screen! N the shake ONLY works rite after I turn it on! It's driving me CRAZY havin to keep goin into the app n pushing the widget shortcut button! Fix that n I'll rate it 5 stars!

Azn. Jan 2, 2016     

love your app but there's only one problem... Can you please make an update where it will support tablets? For example please make it horizontal when opening app and also when using the app booster thing... When I open the box in my home screen it turns the opposite way of horizontal, hopefully you just understood what I said but please add the horizontal thing for tablets or other devices....

Tim. A. Feb 27, 2018     

This App used to be good but lately it just hangs on a blank grey screen when opening and doesn't omoast that point. They need to fix this problem ASAP as I see a lot of other people have this same issue now

SHE. D. Jun 3, 2016     

It's very useful and effective for phone.uc team good job and you all prove that every time.

Ank. S. Sep 11, 2015     

I am also using another app like cleanmaster,Du speed booster, etc but uc clean is best app for clean junk or clean memory i love it.

This app does not works on my galaxy j7 after I updated my phone to marshmallow 6.0.1 . Plz fix it.

Muh. K. Feb 10, 2017     

Its safe. This cleaner not delete cache data (app,game). Another cleaner tool scan cache data app/game. Be aware. You have to know what kind of caches. Data cache, junk cache, residual, temporary. Example: bbm save cache for contact photo's, grub list, photo's grub gallery. If you clean this cache data, bbm will download again this data cache. Thanks

Ama. K. Aug 6, 2016
