Everyone agrees that good health is priceless. And if you can maintain it with tools that cost less than a morning coffee, it's easy, too.

Here are 9 convenient and free (or almost free) apps that will do that and more.

Calling all runners! MapMyRun allows you to track and map your runs via GPS, then share them with your Facebook friends, Twitter following or other MapMyRun users.

The trick with this app? It guilts you into achieving your goals by keeping you honest about our workouts. The way GymPact works: You make a pact of how many days you’ll work out and set the stakes of how much you’ll pay if you don’t. If you don't follow through, you forfeit that money to those who kept their promises. On the other hand, you win a little cash from other truants every time you do work out. Available on iPhone; coming soon to Android.
