Google play store is the BEST android app store available right now.
And I simply love it.
But recently I found out an app store which has paid apps for free(the apps which are paid on Google Play Store)
Although it’s not as rich as Google Play Store(in terms of content) I think that it’s a potential rival for Google’s play store. But still I use it only for getting the paid apps for free.Otherwise Google Play Store is the best it’s the undisputed Champ.
