Phone Cleaner & Junk Cleaner is one of the best memory-optimizing and task-managing apps on the Google Play store. With just one tap, you can clean up all the junk files, remove old caches, and even clean up the browser history. It's a great memory cleaner, and you can also use it to boost the performance of your device.

The app uses the RAM memory of the device to clean up the junk, and it also saves the battery power. This makes it great for use when you don't have an internet connection.

You can set up automated tasks to clean the phone, too. It works great with the automatic settings, so you can leave the cleaning process to run in the background.

The Speed Booster & Junk Cleaner app is highly customizable. You can set the time to run, the type of task, and even the way you want it to run.
