"Intensive cleaning"

Reviewed by / Apr 03, 2012

SD Maid is a system cleaning tool app only for ROOTED devices

Without root, functionality is limited given that SD Maid won't have access to all necessary directories. Even if got a rooted devices, use it at own risk.

This is a Android system cleaner that cleans even the most remote corners. And that's necessary because sometimes, when you uninstall apps, Android OS cannot remove everything and leave data behind (folders, cache, logs...). This data could make the system unstable.

The app is divided 10 tabs. First off, from "Start" tab you'll get general info of your device, specially data usage. It includes a "Explorer" which is a directory. You can move, copy, delete or rename apps. What's more, there's a searcher for contains and root data (root search only available in the Pro version). From "Appcontrol" tab you'll be able to see a list of installed app. Tap one of them and you'll be able to start app, freeze it, remove app, remove app but keep is data or reset app to install status.

"Corpse find" tracks your directory and shows you those folders or files that an app left behind after uninstalling and you don't need. The system cleaner scans the devices known directories with unnecessary files. "Optimize DBs" checks databases and allows you to shrink bloated databased to speed up access and free space. And finally "Misc" from where you can clean Market history, view files that have been modified in the last X minutes or Show top50 biggest files. There are two features only available in the Pro version: Clean apps and Duplicates.

If you're root and want to spare time cleaning up your device, this is a wonderful option. Layout isn't stunning, but perfomance does. And that's what really matters.

Developer's original description available here
This app needs "SD Maid - System cleaning tool" to be INSTALLED!
It unlocks the "Pro" status in the free version, enabling all additional features.

SD Maid is a powerful tool. USE AT OWN RISK!

Nobody is perfect and android neither.
Apps you have already deleted sometimes leave data behind.
The system constantly creates logs, crash reports and debug files you don't really need.
The market leaves temporary files of downloaded apps behind.
Lets not go on here...

Why not get a maid to clean it all up?
SD maid will help you keep your device neat, clean and tidy for you :)!

Please see SD Maid - System Cleaner for further information!

If it doesn't seem to work, try closing SD Maid through 'exit' and reopening it.
In any case you can just mail me and I will help you.

Due to the vast amount of android devices it might not work perfectly on everyones device, but I'm working hard to get it there.
If you have problems on your device contact me ( and I will try to fix your problem in the next version.

Recently changed in this version

Update to acompany the release of SD Maid v3.

    Just what I needed. After trying the free version, knew I had to support the dev and buy pro version. *Edit* I just noticed I have a couple of files left over from apps that I uninstalled, is there anyway this app can delete those?

    This app is amazing! It has easily replaced at least 3 apps on my phone. The only thing I could ask for is an option in the settings to hit "back" twice to exit bc I keep accidentally exiting the app.
