Ashampoo Droid Optimizer comes with fast and powerful file, cache, and app cleaning tools, a helpful Privacy Advisor for viewing app permissions at a glance, a robust App Manager, as well as customizable automatic features, making it a potent and useful app to have.


1-Touch Speed Up: Ashampoo Droid Optimizer's showcase feature, the 1-Touch Speed Up accessible through the main screen or via a home screen widget, quickly cleans the cache and stops background apps to boost your performance. The best part is that it lets you create a whitelist for excluding certain apps from the cleanup.

Robust features: The app packs all the cleaning and optimization tools you need on a daily basis in an accessible interface, through which you can easily clean your Web browser history, manage auto-starting apps, sort and uninstall multiple apps at the same time, and identify suspicious apps based on the permissions they use. All these features work well, are speedy, and integrate with a "Broom Ranking" with achievements for using the scheduler or thrashing files.

Good automation: With the Auto Clean Up you can clean the cache, stop background apps, clear Web browser history and more at regular intervals ranging from 1 hour to 48 hours. You'll also appreciate the reliable Good Night Scheduler, which can automatically disable Wi-Fi during set intervals to preserve battery life, not only at night, but also while you're at work or at home.


Non-material design: While this app looks good, the interface requires too many taps; to launch the Junk Finder, for example, you need to make three taps. If you're used to the expediency of CleanMaster or to the material design of many Lollipop apps, this app's interface will feel a bit slow and clumsy.

Bottom Line

With its solid features, good automation, and speediness, Ashampoo Droid Optimizer is a robust and effective system cleaner and optimizer. While you may not find its design as appealing and intuitive as CleanMaster's or that of other popular cleaners, it gets a big thumbs-up for having no ads or nagging promotions integrated into it. If you're looking for a powerful, ad-free utility, try this one.

More memory, more speed - free and without ads!

Laggy smartphone? Battery always empty? Launching apps takes forever? Boost your smartphone performance and free memory at the click of a button.

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 or each time you switch off your screen. 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.

Full access on rooted devices

Droid Optimizer offers a special feature on rooted devices: Starting with Android 4.3, apps can no longer enable airplane mode automatically. Root access makes this possible again! This way, Good-Night-Scheduler can unleash its full potential and actively conserve energy. Unwanted apps also become a thing of the past, disable or delete (system) apps as needed to keep your device clean.

For all Android devices

Ashampoo Droid Optimizer works with Android 4.0 and higher devices which is practically every device.

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.
