Get a kick out of fitness with this little device. It tracks your steps, distance, and calories burned and allows you to sync those stats to your computer and select smartphones. In doing so, it celebrates how much more you do each day. Zip encourages you to set goals, challenge friends, and go farther; one step at time. That's how you turn everyday life into a social, achievable, awesome path to fitness. By showing you how your day is stacking up, Zip encourages you to get up and go. It helps you make those small changes that can add up to something big. (No wonder Fitbit users average 43% more steps each day.)Zip Tracks:*Steps Taken*Calories burned*Distance travelled Powered by Fitbit's leading-edge accelerometer, Zip accurately captures all-day activity that old-school pedometers can't handle. It bases calculations like calories burned on your personal profile reflecting your stats, not any average Joes. Wear it in your pocket, on a belt, or a bra; this tracker is as discreet or as visible as you want it to be. Its silicone clip will keep you comfortable throughout the day. Zip is also rain, splash, and sweat-proof. With a replaceable watch battery that lasts up to six months, it's excuse-proof too. Zip automatically syncs your information to PCs, Macs, iPhone 4S & 5, iPad 3, Retina and mini and the iPod touch. That means no buttons to push, no data to enter. Just real-time access to your stats and the Fitbit dashboard, 24/7. You can even register and pair your Fitbit devices via select smartphones including certain Androids. Between Zip, Fitbit's free mobile app, and the free online dashboard, you'll get a snapshot of your daily and cumulative progress. Imagine graphs, tools, charts, and a customisable dashboard to boot. Fitbit's goal is to make your data digestible and useful. By knowing how close you are to reaching your personalised weekly goals, you can take those extra steps to achieve them.
