Jawbone Up24: Smart, fashionable & lightweight

The smart and sporty Jawbone Up24 is the most fashionable, lightweight and comfortable fitness tracking wearable you can buy. And it has a beautiful app to match. Some functionality is sacrificed in the name of vanity. There's no display on the device itself for on-demand workout stats or a web-based portal to chart the quantified self data it silently collects. All metrics have to be synced to an iOS or an Android app.

Now, as the Jawbone Up24 name suggests, this new version can truly be worn 24 hours a day without the need to take it off between syncs. Combined with the 3.0 version of its colourful app and newly released Android support, this is one of the top wellness motivators.

Design

This flexible bracelet is coated with the same incredibly smooth non-latex rubber as its predecessors. Beneath this rubber layer, the bracelet has a spring-steel innercore that gives it that deformation-resistant elasticity.

App

Jawbone Up24 is lightweight, but its multilayered app is not. It's full of rich colour, helpful wellness tips plus detailed activity and sleep analysis. Activity is represented by a vertical orange bar that shoots up with more physical movement.

Sleep tracking

Its sleep tracking capabilities chart the traditional eight hours with dark blue, light blue and orange vertical bars on the app timeline. This corresponds to you being sound asleep, restless and awake in bed.

Battery life

Bluetooth syncing has reduced the Jawbone Up24 battery life to a stillimpressive seven days, down from the ten that the original had promised. That's a fair exchange for the added wireless syncing functionality between the bracelet and app.
