Consumes more memory

You said the update would use less space but I had 2.14 GB before the update, after the update there's only 2.10 GB........

My phone has never been faster! Luv how you can keep snoopers out of your messages.

Noah M.

Simple but effective

I was a bit wary when deleting gigabytes of so-called "junk", but my phone's performance has been excellent so far. *edit* too many ads, they also keep prompting you to use their other features, which I was only able to remove by uninstalling the whole app.

It's inflates erased size

Even though it doesn't erase entire cache its says its deletes that and inflates the erased memory size another big issue is every events or festivals or days just o add animation you need to get the tool updated

John Park

Great app and all.


Karen Kaessler

Great App

I love this app. One app that does so much you can delete other apps that you won't need anymore.I recommend you try it.I have it in my Samsung Tablet 3 and Samsung phone 4. Also I noticed they actually read your comments and reply.Only problem is lots of ads pushing products,even ones you already have.BUT the app is still definitely worth having.

Do not download this app!! I loved it for a few months, but with each update, it becomes more invasive. The latest update is a screen lock that appears each time I charge my phone. It shows info such as level of battery charge, temperature, etc. Opening the screen only requires a swipe, but there are ads on the screen, and if you are not very careful, you can end up downloading more junk. Other things pop up all the time. Once I accidentally downloaded a very invasive corner access. I can't get rid of it.

Love this app. The one I've been looking for. It does exactly what you want it to do. This app is worth five stars than all the other crappy security apps. AWESOME. One more thing , I'm going to mention this app to everyone on Facebook , twitter and so on...

Akellah Thompson

It displays advertisement when it asks password for app. When I boost my phone it becomes fast but after 5 to 10 minutes it again becomes slow.

Reynol Sabino

Great Tool

Used to get annoyed when out of storage for updates or new apps. This app cleaned up the dead files and freed 25% more space. So easy to use!

I have no issues with any of CMapps that I have with my Device and let me tell you if I have a problem with any app it's gone so If I am still with CM it's working for me

The Superbgameplayer

I would like to add 2 features to this fantastic app!

I think there should be a 'button' for CPU cooldown and I am not sure if it's there already here,but I would like a place where we could submit ideas for updates.You don't have to do this,this app is amazing already!But I think it would make the app better!

Kshitij Bhusari

It's shame

That you should keep the app lock full of irritating ads. I'd rather if there was an option for a paid version without all the advertisement crap

Claire Lammiman

Excellent app!!

My phone was always over loaded and started to live with storage space running out, but this app has made a quick & simple way of clearing cache & helping me know what is ok to clear or delete. Really pleased with it!!

Fatima Al Khalidi

Too many ads

Whenever i unlock my phone it always take me to some stupid ad why dont u guys make a free ad version , I'm pretty sure people will love to pay for that one

Gianfilippo Cisternino

The Autostart Manager doesn't work any more.

With Android 6.0 Marshmallow the Autostart Manager doesn't work. I do have the Root permission, but the app seems to fail.

Jonathan Geraldi Joewono

Good, albeit bloatwares

I believe people would even pay to get rid of the bloatwares and adwares in this app. Please consider making a premium in-app purchase or something it gets really annoying when you really want to go fast but this app kills other apps so that it can slow the device on its own. Then there should be option to disable things like weather, suggestions and crap. All I want is a cleaning bot, nothing more.
