Fitbit

I have the Fitbit One. I love it. You can track steps, flights of stairs, sleep efficiency... I think it is wonderful. Plus, unlike the Fitbit Flex, you can hit the button to see your status.

I have the FitBit One and love mine!!! I think its more accurate than the Flex b/c it doesn't give false reads/steps with arm movement. I clip mine to my bra and I don't have to worry about it falling out of my pocket or off my hip. Highly recommend.

I have had the flex and the Force,both are great. They tend to work if you hold yourself accountable. Track your food, use the smartphone app and its a great way to MENTALLY be accountable to your own goals.

I recently switched to the Polar Loop cause it can be attached to a Bluetooth Heart Rate Monitor and then display your heart rate in real time on the bracelet. Its the best of both worlds.

It also monitors and tells me when I am not active for long periods of time with alerts that say " Better get moving "

Whatever you buy remember it only works if you put in the work .

ENJOY!

I love my Fitbit Flex. Its nice not having to switch it off clothes and such (I literally take it off to shower and to charge it, that's it).

But warning, I have noticed that it doesn't count Elliptical steps as well because its a smoother step. Mine usually ends about half a mile lower then I run.

It really depends on your preference.

Fitbit One: Clips onto your clothes, is not waterproof, shows stairs climbed.
Good if you can remember to put it on your clothes, don't like things on your wrist, don't want it on your wrist, like being able to click and see your stats.

Fibit Flex: Wrist worn, is waterproof and you wear it 24hr/day except to charge. Doesn't show stairs climbed. Only shows lights and no actual stats (5 lights, each one equals 20% of your goal)
Good if you would forget to switch the One between clothes, prefer something waterproof for swimming activities or instances where water may come into play, like to put it on and forget it, dont mind looking at the app/computer for stats.

Fitbit Force: Wrist worn, not waterproof, shows stairs climbs, has stats on wrist with click of a button.
Good: Like the wrist features of the Flex but rather have the button/stairs of the One.

Personally, I like the Flex because I forgot my One all the time. I like that its waterproof and wore it often while swimming, rowing, boating, etc. I know my basic exercise habits and the lights show me enough data to get by if I dont have my phone. I always have my phone and like using the app so the lack of numbers on my wrist isn't a big deal. The Force is cool but I need/want waterproof.

They all calculate steps in a very similar way. I wore my One and Flex together for a month and overall they were only different by 100 steps total. Some days the Flex would be higher and some days the One would be higher but overall 100 steps different for 30 days doesn't seem like a big deal to me. Not having the stairs climbed feature on the Flex is a bit of a bummer especially because i moved into a house with stairs and feel like I climb those bad boys 100 times a day but I'm fine without that stat.

I have a Fitbit Flex and I absolutely love it!!! I also like the display of the Force but then saw it was recalled, so I obviously couldn't get that one. I am very HAPPY with my purchase of the Flex! I highly recommend it!
