XBooster *ROOT* - Free

My old Note2 suffered from crashes due to memory leaks or poor app devs (Facebook / Messenger), I'd have to restart my phone every other day or suffer a battery pull. Not only has my phone been crash free, but has better battery life. Thank you!

With the right app combination and collaborations to ensure my systems methods are working in its best efforts for the many tech mobiles I test. I appreciate an app as this, verifying the parameters I have retested and reconfigured over and over, ensuring that my security and probability with the tools contributing from Google Store and the developers, work out at its most volatile yet optimistic challenges, especially when I get to explore new tech. So thank you for your work, and please keep developing.

Every other app I think that only shows to clean app. But this app, regardless of ads, have done great things. The modes are working effectively. Hope the whitelist feature could be in free app. But, instead, this a great working application. Recommend to every user. ????

It does work as intended, but it is probably the ugliest app that i've seen for a while. Fix it, so people won't think it's a dirty fake, because it isn't.

Wonderful utility to free memory! Also can set profile for better gaming performance or for multitasking! Free version is all you need and very little ad annoyance!

Can't believe that its works as it says...its optimised your ram quickly and then you checked on your free ram,,I'm on v5.1.1 and its works very well,,its floats my phone instantly,,but UI and software is very old and its not updated since 2013,,but i have no issue for that becoz its do its works very well,,thanks yo devs..

I always had a RAM problem with my device before but thanks to this my tablet plays seamlessly now!

Very useful. It does what it says. Frontline commando 2, lags on my device and now runs smoothly after installing and setting it to game boost/er. Thumbs up!

i like this app, it can boost your RAM unexpectedly! whatever you doing either Multitasking or Gaming.. its stills your phone so smooth.

I don't know how it works, but it solved all my problems!! So happy now :)

I was skeptical because of all of the other ram apps that didn't work, this app works very well. Rooted note 3.

Seems to do as described. Will keep running it for awhile.

This booster ned busy box and busy box is not working.so this app is bullshit.

I've downloaded both versions of this app and it won't work on my phone. I've rooted my phone and it still won't work. I don't know how to get the app working . All that it says is that it would clear some space.

My old model phone is old and extremely slow. This app made it run better than ever

May donate via Google valet only. If you happen to be in Dubai let me know I'll buy you a coffee :) great job thank you very much.

The app does look like it does some wonders. Playing amazing spider 2 and there is less lag.

FINALLY! AN APP THAT ACTUALLY DOES WHAT IT SAYS! Can now play Dead Trigger at ULTRA HIGH GRAPHIC SETTING with a 25 - 30 fps.

I won't say it's the best. There was no significant improvement seen on both game & multi-tasking mode. In fact, there're some apps in my phone which are acting weird ever since i installed xbooster. restore default didn't seem to fix the problem. Different phone responds differently, i guess.

I dont usually give reviews and rating s unless i really liked the app so obviously with this one, it worked for me. Have tried using ram swappers... wtvr exactly you call them, but didnt see any difference till ive tried this app. So yey!

Infinity was running super slow. Did a factory reset, rooted it, uninstalled the pre-packaged bloatware - nothing. Tried Greenify, and similar - slight improvement, but still horrible lag. Installed XBooster - fantastic! I can actually type, surf and do general Stuff without my brain withering up like a raisin. Thanks!

I don't know about battery getting extended. Thus 4 stars. But yes, phone is fast a quite a bit even when I have less memory space left. Its smooth. Have root booster app which claims same; but don't know about it.

Finally I have the app to run my games on HD And very Smoothly. for the root users try this you won't believe How Great this app. and thanks

I've searched for every app that boosted my tab so I could run my game with high specs, but none of them work. Then I stumbled upon this app, and reading the reviews, I decided to give it a try. To my surprise, my gaming experience improved a lot. There is 1 stage in a MORPG game that I played always get super lag to the point that I couldn't move my character and sometimes were forced close, by using this app, I could complete it, even though it still a little lag, but it was way better.

Omg its impossible! My 512 mb ram phone just turned into 1-2 gb ram's speed! KEEEP IT UP MAAAAAATTE!

After seeing the reviews I honestly thought they were bots. But when I downloaded the things work. My phones sucks but with this is actually decent now

If I Could Give U 10 Stars I Would!!! Makes My Rooted Xperia M2 To Play Powerful Games Without Lag. Games Were Laggy Coz I Have Bunch Of Apps And Games!!!

My GTA San Andreas used to lag a lot now it doesn't its awesome :O

I had massive lag issues until I installed this. Now my phone is faster and smoother than ever before. Incredible app. Love it!

Keep tapping "Quick Boost" and MORE RAM is freed up. I have never seen this work on other apps. Some apps will restart, but RAM Stays Free longer than other apps. Make sure and allow system apps to be stopped. It's caused no problems on my rooted phone....

My Lollipop based custom Rom had a terrible issue of memory leak which caused it to get pathetically slow auto restart after every 20-30 mins. But since I have started using this app, the problem is almost fixed! This is a very powerful tool.

I have it but doesn't work it says no root or no busybody anyone help

Well many people commented that it works great but i don't think so.. Because after enabling the gaming mode i checked my ram in settings and it was only 180mb free... And many of the apps become more laggy.. Even my xperia home becomes slow .. Don't know about others but my review is according to my xperia sp..
