Fitocromancy

I'm testing out a few web sites and Android apps, looking for a workout equivalent to Weightwatchers. There are SO MANY to choose from. Lots of people recommended the Nike app, but it's only available for iOS. I am interested in the Nike Fuel Band, so I hope they go Android at some point.

Here's a list of what I'm trying: Runkeeper: GPS-based tracking and mapping of runs, rides, and walks. That's it. I do these activities most, so I've used this a bit already. The fact that I can connect with friends and look up the routes I've walked online or on the phone is pretty neat. Also, it's free. Fitocracy: this was recommended by some video game pals of mine. It's basically achievements for doing all kinds of physical activities. As you do more stuff, you "level up". Workout Trainer: it lists workouts or entire workout programs based on your size, fitness level, and goals. There are apparently 1700 workouts available, including walking for 30 minutes. The other app that was suggested by multiple friends is myfitnesspal, which is a food and calorie tracking app. I already use Weightwatchers (they finally have an Android app) so I don't need it. What do you use, if anything, to motivate yourself and track your progress?
