Task Killer Customer Insights

1. Giving 3/5 ⭐'s because I have checked the apps that are supposed to have been stopped from running in the background after completing the process of killing selected apps and found that while most apps have been stopped, there are a couple apps that turn right back on a couple mins later.Tried many apps that claim this and that, but this app is amazing! Very simple, easy to understand layout.

2. Highly recommend!Very nice but there is no PRO to buy to get rid of all those annoying ads! There's way too many; so many it takes too many steps just to see all the open apps! Will continue searching for another, without all the ads or one I can pay for.Could be good except the auto-kill feature doesn't work because the screen with the "mb freed" message" prevents it from running after the first time.

3. If you're not tech saavy, in one click, task killer simplifies cleaning up nuisance apps running in the background that bog your system down to free up space.

4. I hit kill and it shows all these apps being stopped when they haven't been running in the first place.

5. And it's FREE! THANK YOU DEVELOPERS!! Keep up the good work!!Ive been running this app on my firestick for couple of years and was thrilled to discover it could be installed on my mobile device as well.

6. When killing apps each time you must go down the total list and select which you wish to stop.

7. Then every time you kill a task, you get a full screen ad with mandatory minimum viewing time.Of the many app killing programs I've tried this one stood out.

8. You tell it to close apps and they stay open -- not only in the background, but just plain old open in the task switcher.

9. Wait 1 minute and all those same apps are listed as running again! After I run this all the recently opened apps are still open exactly where they were before.

10. What was wrong with just the message that said how many apps were killed and how much mb was killed? At least put a setting in that lets me turn it off and ill come back to this one.

11. There are programs I have forced stop and/or disabled and they show up on the list to kill.
