Must Have App For rooted power users this is a must have. Going to upgrade to Pro soon. Gives you the full control you should have

A Google User

Has the best support and... ...If you actually know (or learn) how to properly use System Tuner, then you can easily get rid of some other space consuming apps in your phone, 'cause this one is super light, very complete and highly capable. A full 5 it deserves

David Rudolph

????? I've been using the paid version of ROM Toolbox for years and am trying to figure out what I got for almost $7.00 from this app that I didn't already have the ability to due with either that app or paid version of Trickster which I also have. Its probably a good app but EXTREMELY CONFUSING. Don't even consider this if you don't already have a VERY STRONG understanding of rooting, flashing and basic Linux terminology.

Santo Sarkar

First tuning after rooting. My phone is like flying at jet speed after I set the processor on performance mode from hotplug. App does what its supposed to do, thanks guys.

Mark Sullivan

Lots of annoying ads hard to figure out if you want it I have got no problem paying for apps but I like to try or understand what I am buying. The ads to buy are really annoying and while there looked like good things it was hard to figure out what you get in the paid version. Paid for ROMTOOLBOX

David Camden

Limited but effective.

Jude Dahi

Jude Great app. Very helpful.

Thomas Kirkbride

Thomas Kirkbride Just what the hell does this thing do? All I see is graphs, sliders, and confusion. If you like f******, around with do nothing apps, is for you.

William Heath

Excellent.. I used this on my old Samsung S2. Recently got this again and am about to buy the Pro. Thanks Dev

Ryan Scheffert

Miranda Thomas

Good app, bad ads. Strong app, looks like some really good controls. The advert strategy really bites (Fullscreens? Really?) Got too annoyed by the ads and removed. Sorry

Long zhuang

Excellent I have been using this app for several years. It is the best system control app around.

Steven Hutchison

Wow awesome app!! Found the complete app too daunting and bloated. But this collection is perfect!!

Navid Ordouie

System's Swiss Army Knife Perfect system monitoring, Task killer, Kernel log viewer, Backup and more with a complete set of widgets + a Linux Shell! A must-have for advanced users.

Bakari Hernandez

Федул Брондуков

Old interface Was better. Workability was better too

Kuznetsov Stanislav

It was a good application. Interface - sucks, don't work wipe dalvik and reboot. Mtk platform. Too many ads.

Rus G

too cumbersome compared to old system tuner with previous owner.. he has better taste for GUIs too cumbersome compared to old system tuner with previous owner.. he has better taste for GUIs.. freeze/boil should be one touch on app, then one touch on freeze/boil... un-installing.

Nathan Nainggolan

Best tuner app !! This app make my lg optimus l7 getting faster than before, thx a lot. People says this app is confusing, but for me its not. Keep it up.

faysal ashraf

FaYSaL Really Fantastic apps! Luv it !!!

Felipe Luna

App Vary well

Mark Holtkamp

Good As Always! 3c Rocks it. Not sure what the difference is between this and 3c Toolbox. I bought Toolbox so maybe this isn't necessary. Beautiful app either way!

Bill Woolen

SYSTEM TUNER So Far So good, NonRooted phone;Appears Work Better!!Separate Task Killer App., NOT Needed!! TUNER Does that Better!! ??

Beto R

Great! Have been using it for ages..I got the pro version long ago, just passed by to add 5 stars, so now it got 10 stars from me?

a ks

I will give five hundred stars I did a lot of research... I tried many different apps around twenty apps for cleaning and then same for battery stabilize...... Then i found this app which is really superb and it also has battery optimizer ..... So no need to download two different Apps.... One for cleaning and one for battery stabilize...... This works superb

tevia rosmarin

Great utility This app offers tremendous opportunities to customise yourndevice.

Allen Ballesteros

Real battery saver Together with greenify, amplify and system tuner (underclock) your battery will surely last longer.. battery drain during idle time will surely drop.. Thanks for making this app

Wesley Khanh

Good Pro tools for analyse

Don Babchuk

Very nice Only use this, if you know what you are doing. But its worth learning these features.

Abdul Kabir Chohan

I don't know How to use

A Google User

Has the best support and... ...If you actually know (or learn) how to properly use System Tuner, then you can easily get rid of some other space consuming apps in your phone, 'cause this one is super light, very complete and highly capable ON ROOTED PHONES. A full 5 it deserves

VoiceArtistUSA

Uninstall Nah. Not worth $4-5 dollars. Uninstalled.

Kunal Malangave

I like this app

Emil Kamenov

After activating Performance Optimizations: On Boot, phone restarted and after this moment android system apps started crashing, phone lags and restarts every 2min. It is simply unusable!!!! No other app can be started because it just dont start or crash within 5 sec. The phone does not function normally, there is no internet connection, no services, nothing works.The worst part is that I dont even have a option to transfer my music/photos from my phone to any other device! Please, revert with solution? Thank you in advance!

Wary Soul

System Tuner This one is full out great programming - I wish I had skills and patience like this programmer or like these programmers. There is a lot of someone's life and passion all over these codes/this app! I love it and thanks for such a HUGE GIFT!!! OMG BIG!

Seth Raito

I like it But when the app shuts down unwanted running programs it shuts down my music and I have selected music as an exception to being shut down... Can't get it to work property ?

Tammy Kerwood

I love this app. It gives a view of your phone no other does. Many useful tools.

Damon R. Salinas

A must have for rooted power users who like to tweek performance levels of their phone. coupled with 3c toolbox has everything you could possibly wish for. I have Pro on both.... would definately recommend. Try the free version first.. it does just about everything!

Mad Mick

Top stuff Used it on so many phones I have lost count, never an issue, always lets me know what's going on.

MARY ROSE YUMUL

GREAT APP FOR ROOTED PHONE! This is one of the greatest app you need when your phone is rooted. I have a game Clash of Clans accidentally moved as a system app. No app can be found to help me. Others need to buy it or donate first before you can use it. Finally found this , converted my COC game system app back to normal user app. If in anyway I can help you make this more way better, I'll not hesitate to do so. Thumbs up, you did a great job. 5stars!

Madison McLaughlin

UI could be cleaner, easier to navigate. The help articles for each feature are generally useless. ...and the checkboxes in Startuups/Events are ridiculously difficult to check, because the scrollbar lies over top of them; and will be clicked on instead 99.9% of the time. It drives me absolutely insane until I am bloodthirsty and seething with rage.

Nathan Nainggolan

Title This app its not work anymore for me

Angelita Carrasco

This is awrsome Just what I needed. Found out exactly what's wrong. Now what to do with the guy hacking my phone.???

Tom Bombadil

Not perfect, but... Since it's free and it does those few things that I am using it for very well, it deserves 5 from my perspective. Using it for a long time already, had some minor issues, but only in those fields that I am not using often.

Carlos robles

Number 1 I always come back to this app.

Nate Stewart

Information! When you need to know What's Up? With your system! Then System Tuner is the way to go. Scroll through the menus and find out what you need to know. Find out what's going on while it's going on. System Tuner, will show you!

Efraim Blumenberg

Killing Current app This is for the pro version. I bought the pro version and installed. Now it keeps on killing Current apps like WhatsApp or REDDIT in mid use. There is no Extended task killer menu. Although it's referred to in help. I am back to the free version which works fine.

paresh lalta

Very annoying Why do they all demand that you buy the full version . It's so annoying. Because sone of us don't hace the ability to purchase apps on play store

Jordan Sielawa

it changed my cpu to prefomance that made my tablet really fast

ciso banos

Sir how can i reset vold.fstab

Tu Nguyen

Omg this app too many button. I never see any app like this app too many button. I don't know this app work or not but I give you 5 stars

Mansrurd Bloach-Schemauny

Ok app Good colours in, many button to press. Some button named as name s of other phonegame, And cumberlessly down lode. gave all stars !! but pleas --more noises-- is my song of dis satisfaction with this

Back Side

Hm Just started using it. Love the notification bar widget's. :) and the options.

Andrew Wristen

There is no competition This app fully controls CPU/GPU speeds, build.prop.. just everything and the very best is the application event receivers toggles and detailed task manager. There is no other app that will do as much as System Tuner.

Stephen Holmes

Just bought it. Yet to try it out so a 3.

Anthony Illgen

It's good Alot of opinion but work good

Diana Lynn

Great utility app..

Komaki Mills

Joke Jokes should be funny

taha maroof

False app Never download this app. The shown pics are false it wont have gpu manager as shown in pic

private private

Happy user since 2014 Very user friendly. Has tons of options. Is like athe Swiss army knife of android apps. Most of the good stuff are free.

Renae Smith

It's working now, people need a tablet that is more start up friendly that way apps only run when it is opened and is killed when exited it's not fair to the customers of these devices to have to keep working to clear and kill apps to get the best performance... this is why I keep destroying android Phones or tablets What people need is an os for tablets that is more start up friendly that way apps only run when it is opened and is killed when exited it's not fair to the customers of these devices to have to keep working to clear and kill apps to get the best performance... this is why I keep destroying android Phone or other tablet devices... I rent this tablet and it's not worth the money because like all androids you have to clean catch and kill apps once you open them.... people need a good working product and not a casino device. If there's a program to be made then change the last 5 years cause I don't see this problem getting resolved. This is the future of android and weather or not they will maintain their customers.....

Leroy Person

Leroy Person, Jr. This is an app that comes with a load of goodies to help your Android maintain peak performance. For example, gadgets to check battery usage, CPU, memory usage, clean your cache, file management, volume control, WiFi connection and more. It literally tune your Android to a quality that is state-of-the-art, it cuts spending, and saves time. This is an upscale app, and it requires advance knowledge. Help prevent Education crime scams using someone college background for "Thugs" to get rich is a lazy trait.

Phalon4

Systems Tuner I'm very impressed with the features this app contains. I'm even more impressed that this app somewhat turn your Smartphone into a Mini PC with all of it's functionalities. And for those of you whom are complaining about the updates for this app simply doesn't understand the complexities with in your device this app has to maintain and navigate to properly operate due to frequent changes in apps and downloads for current individual's devices.

A Google User

Used to be great Fails to disable some user app start ups.

Nur Ashikin

Likeable It'd be even more if I root this phone. *sigh*.

Asha Kudli Ramaswamy

It keeps my phone clean It keeps my phone clean .I can kill unwanted apps running in the background. It helps for getting battery life more

Steve Mejia

Professional techniques I can see how my PC tablet functions

Who Am I

Not clear what you might be paying for App does not seem useful without paying something to get features. Yet the 2.79 to pay for ad removal does not promise to add features. I didn't want to risk it. Moving forwards, the app as presented seems almost entirely useless. This is honestly how it looks.

Francisco Arroyo

Great optimization I've been using this app for a free years now and I have to say it is great!

Stacy Cutshall

Tuner Don't known
