The Jawbone UP2 is the newest fitness tracker from Jawbone, and is acting as a replacement to its aging UP24 tracker. The UP2 doesn’t try to be something it’s not: it tracks your steps, your sleep, and offers you insight on all of the above. It is not a new experience if you’re coming from an UP24 or first-generation UP, but it definitely feels incredible on your wrist.

That’s sort of the biggest takeaway — for me — for the UP2. It feels amazing. There are times when I don’t even notice that it’s on my wrist, and most people in public don’t think it’s a fitness tracker. And for me, that’s a huge plus.

I bought the UP2 the day it was announced and received it overnight. I was originally dead set on getting the UP3, as it looked quite small and seemed to be a better option than the all-too-big Fitbit line of devices. I had an UP24, so I didn’t need to upgrade, but I wanted to. Enter the UP2.

This thing is insanely small. Have I mentioned that yet?

It feels small on your wrist, it feels small in your hand — it just is small. And I like that. I mentioned the Fitbit line of devices are much too big for my tastes, and the UP2 kind of fills that gap. It fills it really nicely, as a matter of fact.

When compared to the UP24, it just shows how much smaller this thing is.

The band looks, feels, and acts much thinner. I don’t know the exact specifications — nor do I really care — but it’s clear that the band is much thinner, lighter, and smaller. That’s what counts. It shouldn’t burden you or your wrist, especially at night. The UP24 occassionally woke me up in the middle of the night, since the “clasp” on the UP24 would get caught on something — like a pillow — in the middle of the night and would force me to wake up just to remove it from my wrist. The UP2 feels great at night, and that’s what really counts.

Speaking of clasps, the clasp on the UP2 is great. I’ve heard some rumblings from folks that they don’t like it all that much, but it really is something special. It’s easy to put on, it is pretty darn secure, and it just feels good. It’s awkward at first, since it’s not completely obvious where or how it’s supposed to close, but once you figure it out, taking on and off the band is quite simple.

The supplied charger is magnetic and pretty strong. It grips the band right away and is strong enough to be charged upside-down, which is pretty cool. I’ve had no issues with it so far, but I know I’ll lose it — just like the chargers for the UP24 — and I’ll have to get a new one. No big deal.

The top of the UP2 has a few lights on it, and is touch-sensitive. Two taps wake the device and another tap that is held down will change it from “Active Mode” to “Sleep Mode”. I found that this gesture system is really finicky. Sometimes it will not register two taps, no matter how fast or slow they are in succession. I find it easiest to tap the device three or four times to get the “runner icon” to show up for “Active Mode”. At that point you can hold down on the area an additional time to turn it into “Sleep Mode”. I know the third notification light is there, but I have no idea what it is for. Here’s a GIF of the band charging, which shows the lights — including the third and ambiguous light.

The UP2 is a great device, despite its minor shortcomings. It doesn’t have a heart rate monitor, which for me, doesn’t matter. It doesn’t have the bio impedance sensors, which might be nice to have for advanced sleep tracking, but I will live without them. I just love the comfortability of the band and the simplicity. No more stupid tension clasp and no more awkward vibration motor — the UP2's motor is much more “solid”, like the Galaxy S6's vibration motor.

Should you get the UP2? Yeah. It’s $99 and it’s better than any other tracker on the market at that price. Should you upgrade from an UP24? Only if you need something smaller and slimmer on the wrist, then yeah. Otherwise, it’s going to the exact same things as your previous tracker.
