Nike just showed off the second-gen version of its Fuelband, and for the first time, the fitness tracker is coming in a whole slew of colors. Here’s everything you need to know about the improvements. The display is the same, the form factor is the same, but now you’ll have a choice of three shades of neon. It still has a single button and the same LED light. But the band is now sealed better so it’s more water-resistant. It will also give you hourly movement reminders, and you can double tap for your time. The SE has added Bluetooth 4.0, so it can be constantly connected with your phone so you know exactly how active you are always. The app, of course has been updated as well. Within it, you’ll now see an activity curve at the bottom of the screen that shows you how your level of activity has changed throughout the day. Here you’ll see some stats from day to day, week to week, and so forth. Plus, you have options to share activity with friends and add location.
