From the main screen of 9Apps, you can use different filters to find the wallpaper or ringtone that you're looking for, although truth be told these filters don't work as well as they should. Nevertheless, searching by category will allow you to quickly find images of cute animals or breathtaking landscapes, for example.
What should be one of the strengths of 9Apps – downloading apps – actually turns out a bit average due to a simple problem: no applications can be downloaded from within the app. Instead, 9Apps will redirect you to Google Play, meaning it's not particularly useful. The official Uptodown application, on the other hand, does allow direct downloads of APKs.
9Apps is a download portal with both pros and cons. On the one hand, it's good for finding and downloading lots of wallpapers and fun ringtones, but on the other, it doesn't allow the direct download of games and apps.
