Hollow Time

I built a Pebble Time 2 watchface in C and JavaScript to show the time, daily weather, and progress toward 10,000 steps.

Why I built it

I got my first Pebble in high school and liked its simplicity and open source community. When I got a Pebble Time 2, I wanted to build a watchface I would use every day.

Choosing what to show

I wanted the time to be easy to read, with the date and weather nearby. The date pairs the day of the month with the days left in the year: 26/96 means the 26th, with 96 days remaining, excluding today.

A single word, such as Rainy or Sunny, gives me enough weather information to plan my day. A circle around the clock fills as I walk, shifting from blue to green toward 10,000 steps.

Making software for myself

Building this watchface let me choose what appears on my wrist and how it behaves. I’d like more everyday software to be easy to adapt in the same way.

AI has made it faster to build and try these ideas. If you have a Pebble, building a watchface is one way to experiment with software shaped around your own needs.
