The BodyMedia Fit Link armband can track how many calories you burn each day, along with other key fitness metrics like steps walked, and then wirelessly upload it to BodyMedia's web site, where you can set and track your fitness goals. There are also companion apps for iOS and Android, so your fitness data is always accessible. However, unlike similar services bundled with devices like the gdgt Must-have Fitbit Ultra, BodyMedia charges a monthly subscription (currently $7) to access the web site and use the mobile apps. That makes the Fit Link a less attractive option, especially since its upfront cost is higher than the Fitbit.
