Get paid to walk apps?

[b1oldie]

I'm not sure if this is allowed or not, but... I'm wondering if anyone knows of any apps that pay you to walk, jog, run, etc. that:

Don't require you to pay to use them and

Track your steps through your fitbit?

If there's apps that don't require you to pay to use them, but only connect to other watches, I'd be open to those, as well, as long as it's not tracking steps via your phone.

@b1oldie Welcome to the forums. Thanks for reaching out to the community for help with apps that can reward you by walking. 

I personally do not take part on those. However, I have heard of Stepler, Runtopia, Stepbet, Achivement App and Gigwalk. I am sure you can find many more online. Most of them are based on a reward system. I am sure you can find one that suits your needs and interests.
