Wait, that's not right ...
I wear the Nike Fuel band. I get points for activity. Simple enough concept, but it get's better. I have a daily goal. At first, it's a little tricky figuring out just how much more than my normal daily output I need to add to get the point value I'm targeting, but I start walking more, running more and generally adding more activity in my day with the goal of hitting this score. I start getting sneaky about it. I go on walks instead of eating snacks. I take the stairs, and use the bathroom on the next floor so I have to go further to reach it. Soon enough, the goal is too easy to attain and I'm pushing it up.
On days that I work out, I naturally expend more energy, and that's when trophies kick in. I can earn trophies for hitting 50%, double, ... up to triple my daily target. So when I am scheduled for a bit more than a normal day, I can aim for a trophy instead of my resting target, but maintaining my goal performance means on rest days I have to be ready to at least hit the minimum.
It's really well done. Really motivating and useful, and my progress has been a lot steadier with the tool on my wrist. One of the phrases you hear a lot from the LA Fitness loud speakers is "What get's measured, get's improved". I think this holds true for my activity level. I thought it was enough to push it in the gym to cover for my slacking elsewhere, but being motivated to spend more time thinking about being active and working towards a goal is definitely giving me a motivating edge, and as you can read here. The social interaction is also very motivating.
There are a couple of these tools available, some have less features and a lower price tag, but I recommend that anyone trying to push themselves to do more find a way of tracking how well they're doing. Progress, the Phat way.
