Today almost anyone has a smartphone, but not all the android devices out there has a boost, clean or apps booster manager installed by default.
On my testing device, a dual core, 512 Mb ram Android phone I have a small factory app that does the job, but sometimes you need to see if other app is better.
Free Cleaner & Speed Booster is an app that can help you manage garbage files left in you Android device an to see which app is running .
It shows like a Windows task manager and you can see the free storage left, ram memory utilization, cpu load and device temperature .
It has six buttons, scan junk which will guide you and shows you garbage files and help you delete them, a phone boost, a battery saver, a clean whatsapp button than will help you delete old files, only if you want so, a clean history and of course an upgrade one for a paid version !
Tested on my phone I like the design and storage, ram, cpu, temp graphics and the scan junk files that helped me to delete some old cache files .
Clean Whatsapp works great and the battery saver shows how much battery is eating every software .
The clean history button make the app to stop working and also sometimes the app stopped working for no reason . Sometimes also the app shows commercials .
Overall for a free app is a good choice and can be found HERE.
