Some time ago Maya wrote about Sweatcoin app. Here I am going to present you another app, that works pretty similar, but you don't have to do your activity outside - but also at the gym.
Runtopia, cause it's the name of the app, pays you for not only running, but also walkig, doing squats etc. Of course, you earn the most when you move running/walking, because you can turn on time and distance measurment and earn more thanks to daily challenges.
GPS is required, as it needs to count your actuall activity around, but it's okay when you exercise at home or at the gym - it still counts your steps and callories.
What's interesting, you can earn not only with friends, but also by challenging other users. You can also share your results, follow and comment on others' activity - it's something like Facebook or Instagram, but for sport lovers.
Now - what do you actually earn? The currency inside app is a sportcoin. When you collect enough of them, you can ex-change it for gadgets, like clothing, a new smartphone, smartwach, or $500 and $1000 to your PayPal account.
There are three modes of earning sportcoin - basic, up to 50 coins a day, premium, which allows you to get 100 coins a day, and if you connect Runtopia shoes mode - then up to 150 coins a day.
Well, maybe you do not earn fast here, but it is a nice motivation to do some exercise, and if after some time you can earn some money, than why it isn't worth it? :)
