Reviews From google play store

Terrible. I install it open it, run it and tap on device status. The app stops working and doesn't work until I uninstall and reinstall. I try again and the same thing happens.

Samsung Galaxy A50 in this phone of mode action activities must should be auto run permanently. Another USERS TRY TO CHANGE and modify to my Email address also passwords must should be deleted even terminated for permanently. This phone USER also announced that privacy policy and trams and conditions, recourse also dashboards activities always be injustice and illegal. So be definitely stopped. Google and various servers overview, review by changed my Samsung Electronics Galaxy A50 smart phone _

simple to use so this is what makes app great i am older did not have computers as I was growing up very nice to have an app that is easy to use thank you

🔥A great app well thought out job done here.💣 works precisely as it is intended to very nice !🔥

Greatness at its greatest! Application is very smooth with its navigation. Optimizes beautifully

This is superb I love it. I boosted my phone and cleared. Y unwanted files in the phone now my battery status is good

As others said: this app is NO task manager like it is advertised!

Ironic that an app named "Task Manager" has no task manager function. This program does literally nothing that default programs don't

If u play pubg don't install this application .... Because it deletes ur data file like maps and resources packs and u will have to download again Bad application..

I don't like this app at all, this app has cleared all my mobile data

i must put 5☆☆☆☆☆ but it's just my first day using it.i will observe first.if it goes straight working very well i will come back here and give 5☆😘😘but yeah for now i feel it's like my device is working very well 👍👍

Wow, this is working extremely well. I also got the license. So glad I found this by reading some articles I came across. I installed it to work together with their Bluelight filter and both work extremely well. I got the licenses for both.

Nice app

Excellent 👍👍👍





Best app for uninstalling stubborn apps. My tablet started got full. When I try uninstalling some apps, it started acting weird, hanging and restarting etc. I tried several apps. None worked. Manufacturer advised me the painful factory reset. Somehow I had installed this before. And it worked magically. Saved me from factory resetting

It's supposed to delete unnecessary files but it deleted my books from the library in my overdrive app

This horrid app wouldn't even start on my tablet!

Would like to have ignore list for one tap boost (both processes and cache)

Really helpful for boosting device performance & uninstalling unneeded apps.

User friendly, and does what it says

Lovely actually cleanup my device

Best app

Helpfull , easy to boost memory and speed up my phone. Love ur new simple design..

V good


Installing this app before March would unlock the paid version of Bluelight. Well it did, but it reverted to the unpaid version in March. As that was the only reason to install this app, uninstalling now. Do not like this behaviour.

Your phone already has an application Manager that came with the phone. Why would anyone want one thst bas annoying ads, tries to sell you more space constantly. Truly a waste kf space. "Uninstall" 😊


not sure about this one but they keep asking you to install it on the eye filters app,so I don't know don't look at it much its just there for what ??🆗🌞

not sure about this app and what its purpose is, so not alot to say on it sorry 🆕 👌 🆗

can't see the point in Having this app what's dose it do ??

Love that it shows that it is working , also vibrates while it is working

Needs more features

It's up and running

I use it on all the cellphones I have owned.

Cleans real good. Very helpful.

I like it

it's very good. I like it.

not bad


Simple and powerfull



I like the color scheme but features dnt work. Doesn't kill or clear nothing, I am uninstalling it. Its a waste of space......

This app sux. I cannot see it hardly, through the dark filter-like screen usage of it. Then now trying to uninstall through its Uninstaller and it won't let me. Gonna go thru normal uninstall...good thing I have other apps to rid residual (junk). A disappointment. And no 0's in the stars wh/I'd give it

However I do admit that maybe I'm not using the app to its fullest I don't like that it kills apps that I need and that I can't figure out intuitively and easily how to make that happen

Last before not using this app very my device too slow and internal memory not bad because my phone clone phone android 4.4.4 version .now great all clearly and boost in memory,hope you can support help on china clone phone thank you.

Can't see the point in having this app at all what do you get out of it please tell me 🆗🆕🆘👎thanks

I will now use your Ill constructed app.

Create widgets for the app. A widget to clear the memory and this app is 100%

don't understand this app and what its meant to do seem a waist of a app what benefits are we getting out of having it any answer ???

Doesn't show actual storage space the app takes up

It works amazing, but I give it 4 stars because it doesn't keep clean for very long just a short boost in performance

I don't need to go to church any more cause now my phone is god

Try it to get program free....scam app.

It could use MORE of a dedicated battery optimiser!

When using at. Night a big difference for my eyesight

4しし I7 d035 I5 Uninstall 4pp2. I7 5Ux!!

This turned into an awesome program!

Does it have a widget? Please create one

I like it!

I wish. It will work well

Doesn't do anything

I love this app

A widget would be great

Like it so far

Keeps my phone running smoothly.

Love all the CM apps.

Yet unknown💸💴

There's got to be better apps


Force stop
