I have had my FitBit Flex for something like five months now, long enough to grow comfortable with its benefits and quirks and so I thought I’d put together a list of some tips that can help people who have one (or are thinking about getting one) get the most out of it.
1. Wear it and forget it
Perhaps the best thing about the FitBit Flex is that you wear it on your wrist. No need to clip it onto your clothing the way you had to with a FitBit Ultra, for instance. And since the FitBit Flex is waterproof, you can shower with it, meaning there is little need to take it off. This means you can wear it and forget it. You won’t find that you’ve left the house for the day only to leave your activity tracker on the dresser.
2. But set a recurring reminder to charge it
That said, I have found that I need to charge my FitBit Flex every 5-6 days. The battery has only run completely down once. The way I avoid the battery running completely down is by proactively reminding myself to charge the battery.
I use the reminder feature in Google Calendar and have created a recurring reminder to send a text message to my phone every 5 days, reminding me to charge my Flex.
When I get the reminder, I typically charge the Flex in the evening when I am doing my writing and getting the kids ready for bed. It doesn’t take more than 2 hours or so to get a full charge and by the time I go to bed, the device is once again fully charged.
3. Track specific activities
You can (with the latest firmware update) track individual activities with your Flex, which is useful if you want to know some detail about that activity. You do this by putting your Flex into Activity/Sleep mode (tapping it rapidly until you get the two flashing lights). When your activity is finished, you tap it rapidly again until you see 5 blinking lights.
What this does is sets a “start” and “end” marker. Your FitBit is constantly recording your activity and these markers allow you to look at a specific section of that activity to see the details. When you log into the FitBit dashboard, you will see those activities listed in the day on which you captured them. I’ve used this to capture the distance of my walk from my house to my office, for instance. Or how long a particular hike took. Here is what an activity record looks like for my lunchtime walk, as seen from the FitBit website dashboard:
