Wearable personal trainer.
The Fitbit Flex Activity Tracker acts like your own personal wearable trainer you always can carry around. It measures your activity level at daytime and monitors your sleep quality at night. That is something a real personal trainer wouldn’t do.
Update 2018: Check out the cool Fitbit Ionic.
The wristband is supposed to be worn 24 hours a day and is targeted towards both beginners and experienced fitness people that want to maintain their shape and health. Fitness wristbands have really become popular this year and motivated people to walk or run just a little further.
The activity tracker wristband is made by a company called Fitbit based in San Francisco. They have several other wearable activity trackers in their portfolio like the Fitbit Zip clip and Fitbit One. The Flex was launched in 2013
They have received many awards for their products including the ‘CNET Best of CES 2013 Award Winner’ and the products have many fans that love the intuitive design and simple functionality.
How Fitbit Flex works
The tracker itself is a small removable piece you put inside the rubber band. You attach the gadget to your wrist and then it starts to log your activity. It measures your steps, distance, how many calories you have burned and how many minutes you’ve been active. The sleep monitoring keeps track of the quality and how many hours of sleep you had.
All this info is synchronized via USB to your free Fitbit account or via Bluetooth to the free smartphone app and you have all the statistics in your hand. You can make diagrams and add stuff like what you eat, your weight goals, blood pressure, and heart rate.
You are supposed to wear the wristband 24 hours. It can even wake you up, and only you, with a silent vibrating alarm. That is pretty neat.
5 small LED lights show the daily progress. You decide your daily goal in advance and each light illuminates when you have reached 20% of that goal. So if you miss a light you know what to do. When you reach your daily goal the Flex vibrates to let you know.
The wristband comes in two sizes: Small 140-176 mm and Large 161-209 mm. Both follow in the box.
Software and Apps
On a PC you download and install the Fitbit Connect software and make a free account. You use the accompanied USB dongle to synchronize to your PC.
On smartphone and tablet, you download the free Fitbit App for either Android or iPhone/iPad/iPod. All the data is synchronized via wireless Bluetooth. You can track your progress and compete with others.
In addition to show you your training progress the LED lights also give you feedback on the battery level. The battery lasts for between 5 to 7 days before you need to recharge it with a USB connection. It takes between 1 to 2 hours to charge.
