App Killer and Manager Customer Insights

1. It is the only app I've found that comes close to the performance boosting available in Android 12.Out of the at least four app killer/task manager apps that I personally have used, this one is by FAR the VERY BEST! It looks GREAT visually/style-wise, it is incredibly simple & easy to use to the point of being practically IDIOT-PROOF, it works VERY fast and is extremely low-key with it's adds and stuff.

2. OH! AND it is ALSO a VERY DECENT FILE MANGER AS WELL! Which is EXTREMELY cool, not to mention very convenient too! So if you are looking for a task manager/app killer, look no further!There's "contains ads" and there's "spams you to death with them." Had to get through 3, including one with a countdown timer, just to get to the app killing screen, which didn't kill any apps.

3. Then I ran thru a short list of user apps running in the background.

4. This was my favorite memory boosting app for months, but lately it only stops maybe 3 out of the over 30 apps it used to stop from running in the background.

5. Makes you work in detail about your white list choices, but in return is very informative over your apps.

6. Because the phone makes it harder than it should be to close apps running in the background.

7. I ran thru a full list of apps and added numerous to my white list (to be ignored and allowed to keep running).

8. It's better than others app killers I've tried, which close apps only momentarily because they just reopen right back up! This App Killer won't let them do that! 👍I'm using this on my Kindle Fire 10.

9. So far, so good at the start.The app has an advertisement pop up during the phases of selecting buttons to turn off apps and cleaning caches.

10. Suffers from the same issue as everything else tried so far on my Xiaomi Note 8: says it needs permissions and then takes me to a settings screen that doesn't have the required options on it.I have a Motorola phone.

11. One problem I wish you could fix is the way the apps close on Motorola the app has to close them one by one and I ha e to wait and watch as every file gets opened.
