Only 4⭐ because I'm not able to control the list of processes or apps stopped. Im using a Lenovo tab M10 ,!model x606f on Android 10. I wish I could access the auto start and stop the bloatware from using my ram up in the background while I am trying to play games or stream television shows. It definitely works to free up useful memory, but im not sure for how long. Id really like to see whats happened or know more about it's settings and features not known

Well, now it doesn't work at all as it use to back several years ago and instead when pressed opens random app and crashes the phone. Same goes with fast task killer which doesn't do anything what it says in its name. Lost and gone to dead apps. RIP. If dev you are reading this, then consider what u have said or else u can do whatever you are doing these apps to go downhill.
