What is your best Android Cleaner App


What is best Android cleaner app ? like the Android eraser , Erasephone and SD Maid are good at deleting or cleaning up Android everything completely , but they are not free ,i used to use the SD Maid for 1 yeas , but now i am using the Android eraser ,nice


Its not necessary since system/android itself can do it


You know , these data can be recovered back after them be deleted or these data can not completely delete from your phone if the Android does it .


I understand that fully, i just don’t see a reason for an eextra app
