Fit Bit One v Fit Bit Zip

I have the FitBit One also and love it. Really gives me a true reading as to my activity level and lets me focus on being active.

I no longer guess at how many calories I burned lifting, walking, or biking, I know exactly and using that number helps me to stay in a calorie deficient and lets the weight come off.

I have the Ultra (which is the precursor to the One, I think), and I bought the Zip for my partner.

The One and the Zip both sync with a USB dongle and wirelessly. The Zip is battery powered, while the One is rechargeable.

The One tracks calories, steps, distance, stairs and sleep, whereas the Zip tracks steps, distance and calories (but no sleep or stairs).

If sleep or stairs is important to you, definitely get the One. If having a rechargeable battery is important to you, get the One. If you only want to track steps, the Zip is fine. The extra $40 in price gets you two additional functions plus the recharging feature on the One, but only you can say whether the cost is worth the benefits.

Enjoy!

I have the One and LOVE it! It is smaller than the Zip, tracks sleep & floors, and it also has a silent alarm which is great when you don't want to wake your partner or when you have to sleep with earplugs in but wouldn't be able to hear the alarm clock go off.

I had the One for about 6 months and have the Zip now.

I recommend the Zip to everyone for these reasons:

1. The Sleep record is completely unreliable on the One. I never used it, left it on my dresser or in the charger overnight, and still constantly woke up with it having registered that I'd woken up frequently. I have no pets allowed in the bedroom at night, and I am not in an earthquake zone, so unless my dresser goes for a jog while I'm sleeping, the sleep tracker is pointless.

2. The Stairs tracker is also completely unreliable.
Example A: My husband and I would each wear our Ones and go on the exact same hilly hike. He would register 86 floors and I would register 52, or vice versa, and the numbers were always completely different even though we hike the same trail all the time. It actually ranged from ~30 to ~100 floors depending on its mood.
Example B: I used to take a Zumba class that was on the second floor of a building. The damn thing registered every step I took as if it were a stair step. I'd leave class with credit for 100 flights of stairs I hadn't climbed. I got all kinds of crazy stairs badges I never earned.

3. The long, thin profile of the One makes it less obvious in more outfits if you wear it BFC (Bra front and center) like I prefer to, but it also made it prone to being pushed askew every time I bent over. I lost two of them completely, but I also had it fall out of my shirt many times when I did notice and had to pick it back up. The Zip is a little lumpier, but it does not have that problem.

Mind you, I love the Fitbits in general, but the One was really annoying.

@tstone212, it rarely needs charging and it charges pretty fast. I'd just plug it in overnight when it was getting low, but even 15 minutes in the charger would hold me for another day or more if I was in a hurry.

I looked at the One, Zip and Flex. I ultimately decided on the Zip for several reasons, and I'm very happy with it.

1. I didn't want the Flex because I don't like wearing a watch or anything on a constant basis - and I didn't want added tan lines.

2. I don't care about sleep patterns or number of stairs climbed.

3. I think the bright pink zip is cute.

4. Zip is cheaper and does everything I need it to do.

I wear it clipped to my bra, and very rarely need to adjust it so that it doesn't show under a shirt. Hasn't been a big deal for me.

I have the One and I am totally in love with it!
