Goals and Tracking
Flex uses LED lights to show you how you’re stacking up against your daily goal. Each light represents 20% of your goal. You choose which one – steps, calories, or distance. It lights up like a scoreboard, giving you the motivation you need to get up and keep moving. Just check your stats right on your phone.
Wireless Sync
Flex syncs your info to select Bluetooth 4.0 devices, without plugging in or pushing buttons. It also syncs with select Android devices (Samsung Galaxy S III, Note II, and more), as well iOS devices (iPhone 5, 4S, iPad 3rd gen., iPad Mini, and more) and PCs and Macs. This gives you real-time access to your stats on the Fitbit dashboard throughout the day. Plus, with select NFC-enabled Android phones, simply tap your device to launch your Fitbit stats.
Compatability
Flex syncs with popular fitness apps for an integrated fitness regiment. Apps include Sparkpeople, LoseIt!, MyFitnessPal, MapMyFitness, Runkeeper, and Endomondo.
Logging
Log food consumption, weight, and weight changes, and additional workout info on the website and on the go using the Fitbit App for iPhone and Android.
Helps you get your Sleeps
Flex never sleeps, even when you do. Continue to wear it all night and it’ll measure your sleep quality. Your dashboard will reveal how long you slept and the number of times you woke up to help you learn how to sleep more soundly. Flex also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner.
Flexibility to match your style
Flex tracker is flexible. You can take this tiny tracker out and put into any of Flex's colorful bands to fit your mood. Check out our accessory band colors and look good no matter what you're wearing.

First things first: If you fasten/unfasten the clasp a few times (it took me 3 times), the holes in the band will loosen up and the Flex is very easy to take off/put on from that point forward. The very first review of the Flex here made that point quite clearly.
Second, there is a reason there's no manual: generally, people don't read them. That's why you need to go to the website to initialize your Flex, and, hopefully, read the other instructions. FOR EXAMPLE: If your results are really inaccurate, you may need to change the default from Non-Dominant wrist (sensitive calibration) to Dominant wrist (less sensitive). [My experience: I'm using it on my non-dominant wrist, and I spend much of the day on the computer. I'm right-handed, and that's the hand I use for mouse/touchpad. My Flex is on my left (non-dominant) hand, and my results are well within my expectations for other movement.]
Third, MEASURE YOUR STRIDE. If you walk, as I do, try this: Put a pencil or other straight object on the ground, just behind your heels. Walk 10 steps, bringing your heels together on the last step. Put another object behind your heels. Measure the distance in inches between the two straightedges and divide by ten. Bingo: You just got a fairly accurate stride. If you are a runner, run a known, accurately measured distance, **counting your steps.** Divide the distance by steps and convert to inches.
No, the Flex doesn't have an altimeter, so it can't measure "flights of stairs." (Neither can the One, actually: it measures 10' changes in elevation.) But nothing in the Flex's literature should have given you any impression that it has an altimeter. So not having something it never purported to have, is not a problem with the device.
If you do even the most basic research, you'll know the Flex only syncs via Bluetooth to a very, very few Samsung devices (two or three, I believe) and iPhones/iPads. On the other hand, it doesn't suck your Android's battery if you can't sync via Bluetooth. It takes _maybe_ two seconds to sync to my computer via the USB device, and by the time I look at my phone or tablet, the updated info is in both the Fitbit app *and* MyFitnessPal. (If you really want to sync to your phone or tablet, there are cables available to accept the Flex's USB dongle, and plug into a micro-USB port.)
Before getting my Flex, I was using the Android app CardioTrainer. I'm still using CardioTrainer, because (a) it's on my phone and (b) I get to listen to music while I walk. The step counts between the Flex and CardioTrainer are within 1 percent of each other (using the same stride length, and having the phone in a back pocket).
No, of course the Flex isn't a heart-rate monitor. So no, of course it's not going to *precisely* tell you how many calories you've burned. But the algorithm should be useful for the vast majority of people. If need or want pinpoint accuracy, then yes, you need a heart-rate monitor.
Bottom line: For what it is intended to do, the Flex is as close to perfect as I could ask for. Everything I expected it to do, it does, and very, very well.
