I tried an app called ME PASS and it really is excellent!
Today I withdrew 12 dollars from it easily after collecting coins from daily tasks. The app gives you a currency called MEC, and each unit is worth about 4 dollars.
The nice thing is that you can earn more when you use a referral code, I personally used this code:

I recommend you try it for yourselves, because it is really simple and tested, and many people have started to benefit from it. It's not a loss to try, especially if you like apps that provide a little income without capital.
