I have to share. I found an app that actually motivates me. Not only does it track my distance by GPS, accelerometer, or by manual entry, but it makes me want to run more and more often. I find myself sneaking away to get in a few more minutes here and there. And, it is fun! I give you Zombies, Run! 2. It tells a story and your playlist intermingles with it. You are smack dab in the middle of the zombie apocalypse. You must gather supplies, go on missions, and help build up your township. While on missions, they seem to be about 30 minutes each, if a zombie is near, then you must pick up your pace to outrun them.
