Do any of the fitness bands have Windows Phone apps?

I was reading about the Fitbit band, the Jawbone Up, and the Nike Fuelband and thought that it might be helpful for me in my exercise/activity goals this year. When I visited the various sites, none of them advertised Windows Phone apps, however, and some didn't even have Android apps. I own a Lumia 920, and I'd like an app I could use on my phone.

The other option would be to use my iPad 2, does anyone know which of those fitness band apps are tablet compatible? Finally, the third option would be web browser tools. I'm at work most of the day, do any of them have all their app data on the web as well?
