Wireless sync to PC and Mac
Fitbit’s trackers are the first all day activity trackers to offer Bluetooth Low Energy connectivity, so you see your stats in real-time.
Syncing occurs automatically any time Flex is within about 20 feet of the wireless sync dongle and is relatively motionless. The dongle plugs into your Mac or PC’s USB port. Syncing and uploading require use of the Fitbit Connect application.
Wireless sync to mobile
Syncing Flex™ to your smartphone or tablet requires Bluetooth Low Energy. This allows your Flex to sync wirelessly and automatically with a wide range of leading iOS and Android Smartphones.
For a full list of supported devices, visit: https://www.fitbit.com/devicesIf your phone does not support Bluetooth Low Energy, you’re still in luck. The Fitbit mobile app works with all smartphones for logging data, receiving notifications, and viewing graphs and charts based on your last sync
Memory
We recommend syncing your data regularly. As long as Flex has battery power, it tracks the most recent seven days of detailed, minute-by-minute data. It also tracks your daily total for the past 30 days and summarizes your daily calories, distance, and steps taken.
Batteries & Power
Flex battery lasts approximately five days when fully charged. When charging your Flex the LED lights will indicate its level of charge. All 5 lights will light up when it’s fully charged. You can also see your battery level on your Dashboard and mobile application. Remember to charge your Flex every 3 to 5 days to ensure you are always tracking.
