Description

A radial bar graph watchface - time and energy flowing clockwise around your wrist. 

Hours stack clockwise from the bottom left
Minutes stack clockwise from the top right
The left outer ring tracks your steps
The right outer ring shows your battery level


Radium started as a sketch ten years ago: what if a watchface was a radial bar graph? Minutes filling clockwise on the right, hours on the left, battery and steps wrapping the outer ring — all of it readable at a glance without a single hand or number in sight.

Back then, two generous developers, MathewReiss & MicroByte, helped bring it to life. Now, with a little help from Claude, it's been rebuilt from scratch for every Pebble platform — including the new Pebble Time 2 and Pebble Round 2 — with full color customization, 24h support, and a few new tricks.

**How to read it:**
The right half fills with minute ticks as the hour progresses, grouped in fives. The left half fills with hour blocks. A thin outer ring is split between battery on the right and daily steps on the left, both rising from 6 o'clock toward 12. In the center: day, time, date.

**Shake to reveal:**
The overlay starts visible — it reads like a normal watchface. Shake your wrist and the digital readout disappears, leaving the pure radial display. Shake again to bring it back. Every reboot resets to visible, so it always makes sense on first glance.

**Features:**
• Radial bar graph — minutes, hours, battery, steps
• Shake-to-reveal art mode
• 9 independently customizable colors
• 24 presets across Dark, Light, and Color themes
• 12h and 24h support
• All 6 current Pebble platforms
• B&W layout with invert option for Aplite, Diorite, and Flint
