Against data chaos
Installed apps, downloaded files, images, music, videos - over time, your smartphone will get cluttered leading to noticeable slowdowns. Ashampoo Droid Optimizer frees your smartphone from clutter and reclaims free disk space and performance - regularly and fully automatically. Need to constantly delete a folder anew? Simply add it to 1-Touch Speed Up and Auto Clean Up. This feature is also supported by Junk Finder!

For your privacy
Browsing the Internet with your smartphone leaves various traces that can be used to violate your privacy. And let's face it, do you really know all the time what device permissions your installed apps have? Get rid of Internet traces and expose potential spy apps with Ashampoo Droid Optimizer.

For prolonged battery life
The integrated Good Night scheduler can disable features such as WLAN or mobile connectivity automatically during customizable time periods. Put your smartphone to sleep at night and conserve precious battery power with Ashampoo Droid Optimizer.

With fun and motivation
Cleaning doesn't have to be boring. The integrated ranking system provides rewards and funny pictures for your achievements. Start out as a mere cleaning rag and become a master in no time. You can also select more neutral ranks if you prefer that.

Free and without ads
Ashampoo Droid Optimizer is and will remain free to use and without ads.

Are you missing highly important features such as Game Booster or CPU Cooler?
What others won't tell you: It's not that easy! Lowering CPU frequencies requires root privileges and although your CPU may stay cooler it will also perform much slower. What is possible is closing unneeded apps to free as much memory and processor resources as possible - and this is what Auto-Clean and 1-Touch Speed Up already do extremely well. You see, Droid Optimizer doesn't need much advertising but lets actions speak for itself.
