Apps & Games content ratings on Softonic

Content ratings help you understand the type of content you might find in an app or game, so you can decide if they are suitable for you and your family.

What do the ratings actually tell me?

Content ratings describe the minimum age we feel the content is suitable for. It does not indicate that the app was specifically designed for that particular age, or if a certain level of skill is required to play the game or use the app.

Where can I find the content ratings?

You will find the content ratings on every app or game page.

Why are some apps or games unrated?

If an app or game does not have a rating, it means that it has not yet been rated, or it’s been rated and we’re working to update the page.

Rating Systems

Softonic uses the rating systems by PEGI and ESRB. The ratings you see may vary by country or region.

"Shovelware by ASUS in Lollipop system upgrade"

Cheetah Mobile convinced ASUS to put a stub to their app in the Lollipop upgrade. Problem is, the stub is marked as system app, and no matter what you want itsceither got root privlegesctomyour device, or you will be endlessly hounded to "upgrade" (install) it. Other apps got this special treatment, 50+ Games, TripAdvisor and Zinio. Aside from there not being any benefit to using Clean Master with Android 5, it extends the surface of malware attack. The app itself has no integrity checking to prevent being coopted by malware, and it RUNS ADS This is something that I find acceptable in a trial free app that can be removed, but absolutely odious in a manufacturers package system update that never notified the device owners didn't ask permission to install, and cannot be permsnently removed or disabled.

  • Needs effective retraction of system app right and total removal
  • Needs to uninstall stub included in system update
