More memory, more speed!
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.

Droid Optimizer works great, and it can be fun to use. My original review was incorrect because I confused it with another phone optimizer app I've been using for years. My bad. I'm so sorry, truly! My phone crashed and was warranty replaced. It didn't transfer all as original but still a great tool I use daily. Some app has decided to save my battery by shutting off my Bluetooth every few minutes. Like while I'm on a call. I don't recall turning that and I can't find which app to turn it off.

Hello! Alright, thanks a lot for the update! You can check which apps actually have a permission to toggle bluetooth on or off. The easiest way is through the Android settings. https://support.google.com/android/answer/9431959?hl=en

Excellent app, although I don't understand each part. I like the way it interrogates the system an displays which program has access to parts of your device. Plus I'm able to adjust which programs closedown. I'm still trying to figure it out, but it appeared as programs were closed, an as I rebooted them, I was able to see if the program was problematic. It would probably be a more excellent program if it was straight forward & explained how to run each part. But I still highly recommend it !

I've been using this for a month or so, and it has done everything I had hoped. I was looking for a simple cleaner that wouldn't cause more problems by using graphics to animate what's happening (like certain other apps do) and would actually make a noticeable difference in the smoothness of my phone operation. Droid Optimizer fits the bill! It's easy to use, and it has one unique function unlike the other apps I had tried: auto clean. It's perfect!
