The FitBit app for the iPhone and Android makes it very easy to pair the Zip with your phone and you can easily sync it by tapping the refresh button within the app. Beyond displaying information from your Zip, you can reset your daily goals, share your progress, and log your food and water intake within the app. Because it uses low-power Bluetooth 4.0 to connect to the phone, FitBit says you should be able to sync the device with your phone multiple times on a daily basis without draining the battery of the phone or the device. The Zip holds a small circular battery, which lasts 4 to 6 months. You can check the battery level in the app and on Fitbit's website; after three weeks of use, the battery on my review unit still reads full.
Smiley face aside, I found the Zip to be just as motivational as the previous FitBit Ultra. I found myself checking the number of steps I'd taken often in hope of beating my 10,000-step daily goal and even walking more to rack up the steps. If personal competition isn't enough for you, you can also compete against your friends and watch how you compare to them on the FitBit Leaderboard.
There are some things the Zip doesn't have. FitBit is saving them for the new $99.95 FitBit One, which will have a stairs-climbed counter, sleep tracking capabilities, and a silent alarm that vibrates you to wake you. But if you are looking for a simple fitness tracker that's easier to conceal than others from Nike or Motorola and now has mobile integration, the Zip is worth the $60. And now it's once again a few steps ahead of the competition.
