So far, I have tried a number of apps on my old phone, a Galaxy S5.  New phone is a Samsung Galaxy Note9.  

Now, I had tried Mistplay and also tried Just Play.  Just Play is like the other apps, except instead of downloading whatever games are popular and out there, Just Play has a few games of their own, which you download and play.  My favorite game is Treasure Master and it is the easiest game to play. A monster, resembling a ball, spins on the screen and you shoot arrows/spears at it.  When it takes enough hits, it dies.  You get roughly 2000 points per round and after a few rounds you watch an ad.  For every 80,000 points you earn in the games, you get 1 penny.  While it may not seem like much, I was able to earn $4 in less than a week.  Some days, I wouldn't even open the app and it would reward me with coins.  This past month of August, I received $8.02 to my Paypal.  I would bet, that if I spent the same amount of time as I did with Mistplay, I could earn as much as $20 with this app. 

There is a counter and if you get to the minimum payout amount, within that time, it will send the cash to your Paypal.  Right there, no waiting, no days, no orders. 

Pros:  Games pay coins quickly and you can earn pennies quickly.  Also the amount does go to your paypal account rather quickly; I believe I got mine in less than 24 hours every time.

Cons:  The games are tedious.  They only have THEIR games so playing the same game and watching ads for a week straight to get $1 worth of coins can be a bit much on your brain.
