For Indian users, there is an app known as Pocket money. Though lot of times they don't pay out. Instead they make excuses as expired or so. I think you can see that some of the time it is not easy to make money through apps. I do suggest using beer money forum for something decent though. Reddit has listing for such apps in their beer money reddit. And there is also subreddit where they show apps like Perk. Perk is legit money making app.
