Straight lines, easy to read layout, and nighttime displays. The lines by each statistic fill (right to left) with the accent color as you achieve your goals.
Version 1.1 adds a dual-timezone mode, choice of 12- or -24-hour time display, more font thickness options, and phone-based settings to control colors and time displays.
Tap the time to cycle through the five font thicknesses; double-tap the time to switch between single and dual clocks.
Tap the bottom of the display to switch between the steps/floors/distance stats and the heart rate/active minutes/calories stats.
A few hours before bedtime, the accent color changes to orange (less blue light); just before bedtime, the display dims slightly; after sleep the display dims a lot. Dimming ends near your wake up time and the daytime color returns an hour after your wake up time. You can choose the colors, sleep/wake times, and secondary timezone from Settings in the Fitbit app on your phone, tablet, or computer.
