You know what they say: A dog is a man's best friend. Perhaps that's why quadruped pals (and I don't mean cats) make the best walking or running partners. A dog's gotta walk, right? And you need exercise. So why not combine a little bit of exercise, some canine energy and maybe even a little charity?

Walk for a Dog, developed by WoofTrax Inc., allows you to record your dog walks and, for each mile you walk, the app will donate to an animal shelter or rescue organization of your choice. The more walkers a certain organization has, the more money the app donates. You can even record the names of the creatures you're exercising with, so you not only have evidence that you exercised (so you can prove your mom wrong, of course), you also have proof that you are a charitable person who loves animals.

Find this app at Google Play and the Apple app store.
