Charity MilesIf vanity or your health aren't motivation enough for you to go out and exercise, why not do it for somebody else's benefit?
Charity Miles just keeps on giving as it allows users to donate money to participating charities based on their amount of physical activity. If you think that you feel good after exercising, imagine how good you will feel knowing that your workout has raised funds for charity?
The app awards 10c per mile to bike users and 25c to runners and walkers. It's a basic distance monitor which makes use of your phone's GPS to measure distance travelled. You don't necessarily have to strictly use it for planned exercise either. You can turn it on if running for a bus or taking the dog for a walk.
