I came across an app a few weeks ago called Sweatcoin. Right now it seems that it is only available for iphone, but from what I have been reading it seems they are about to release it for Android as well.
Basically, it is an exercise app that counts your steps. For every 1000 steps you take, you get a Sweatcoin. You can use these coins to buy things from their in app store. Other people who feel that Sweatcoins might be worth something someday are selling and/or trading them on the Sweatcoin subreddit, which you can find at the link below.
If you would like to try the Sweatcoin app for yourself you can get it at the link below:
I have found the app addictive. Having no car at the moment I have to walk anyway, but that being said I walk extra to generate more coins because I am one of the people who like to trade them. Well, I don’t trade all of them, I keep some as well. I think anything that gets people more active is a good thing anyway.
Side Note: When I walk to the store at night I have to pass a local cemetery. Last year I use to hang out in there all the time and walk around. I LOVE cemeteries!! I find them so peaceful and relaxing. Anyway, tonight as I passed it in the dark I took a quick photo.
