Not bad at all. Sometimes gets stuck trying to force stop apps and starts to get in a loop of just pushing the same force stop option over and over again without giving it a second to actually happen. Hitting the back key on your phone usually snaps it out of this process. I am using this on a samsung galaxy s7 and it helps a ton.

Easy to use, very simplistic. But that's what it lacks, cpu/ram usage stats not available, subprocess trees not available. Basic as it gets and has a lot of ads for what it is...I could put that app together from written code in about a day. They could have made it a lot better

Used once, it worked as expected, killing the list specified one by one. immediately afterwards, i killed the app, and made sure to disable data usage and limit background use. Upon checking it today, it used 3.14mb data, and used 41% battery since my phone was last charged Something sketchy about this.
