The main purpose of the Fitbit Zip is the same as its predecessor: to calculate your activity level from the steps you take. It then uses that basic number to calculate the total distance traveled and calories burned. The device also displays the time, plus a playful smiley-type icon if it detects you're moving. If the Zip senses that you are getting "lazy," however, his smiley face will let you know. Since there are no physical buttons on the Zip, you have to press them to scroll through the various menus.
One of the most useful new features featured on the Fitbit Zip is its ability to sync wirelessly over a Bluetooth connection. This is a big improvement over the company's previous products, namely the Fitbit Ultra, which required a heavy USB cradle, connected by long cable to a PC, to transfer activity data.
In fact, the Fitbit Zip,
Fitbit One , and the upcoming Fitbit Flex, use a compact USB adapter, more suitable for laptops. Additionally, the Zip supports data sharing (also via bluetooth) with iPhones via the Fitbit iOS app. This means that you will be able to have your statistics updated in real time as long as your phone is on the network. Android users are supported by an Android app, but Bluetooth sync between phone and tracker is only available for Samsung Galaxy S3 and Galaxy Note 2. Fitbit has also recently improved its smartphone app, both on Android and iOS, bringing a more graphic touch to the interface. Indeed, while the home screen displays information such as current measurements taken, calories burned, weight, and so on, when you turn the device in "landscape" orientation opens a interactive graphical view.
You can view steps taken, distance and calories burned on the Zip itself, so you never have to wait for data to be transmitted to the PC.
To use the Bluetooth wireless connection, download the free app, whether for iOS or Android. The device works with Bluetooth 4 / Bluetooth Smart and apps are available for iPhone, iPad and iPod touch, Samsung Galaxy S III and Galaxy Note II. Then simply create a free personal account on Fitbit.com to track your performance. Premium accounts are also available for personal coaching. However, you will need to create a second account if you already have an account associated with another device of the brand. To use both Zip and Ultra, for example, you need to create two accounts, each with a different email address.
What you get with the Zip
The number of steps calculation : The pedometer follows precisely the steps, reset every day at midnight. You can see the total daily step count on the Zip ap. The website renews the data every five minutes of the day.
Distance : This is estimated from your height and gender, but you can enter a stride length on your profile to use instead. (How to measure the length of your stride?)
Calories burned : The screen displays the number of calories burned each day, since midnight. This uses your basal metabolic rate and activity to calculate it. You can add other activities (besides those recorded with your Zip) using the Fitbit app or the website, these calories will be added to the total during synchronization.
Time of day display : Who needs a watch? But no alarm or stopwatch.
Fitbit Smiley: A face shows different expressions depending on how active you are.
You earn rewards for milestones such as daily steps, total steps, distance traveled, etc
Visibility: the data displayed on the screen is visible even if it has no backlight for nighttime use.
What you don't get with the Zip
There is no stopwatch function to track individual workouts, there is no monitoring sleep quality, and it is not able to calculate data for stair climbs (other than steps it is already calculating). You also cannot see your performance from the previous days directly on the Zip, you have to go to the site or the app to see this data.
Diet Tracker
You can use the Fitbit app or the website to track what you eat and the balance of calories consumed versus calories burns.
You can track your weight by entering the app or using their Aria WiFi scale. Fitbit works well with other online fitness sites and their health tracking databases. You can choose to export your data to Microsoft HealthVault, Fitbit, Endomondo, SparkPeople, Nike + and more.
Fitbit and social media
You can connect with other Fitbit device users and choose to share data and challenge each other others or choose to send your data daily or weekly through Facebook or Twitter, and get a weekly summary by email.
