How Boulder grows

⌨️

Pick what you're focusing on

Code. Write. Read. Audio. Design. Each kind of focus stamps a different texture into your Boulder.

πŸͺ¨

Hit Focus. Watch it grow.

Pixel by pixel, in real time. The longer you focus, the bigger Boulder gets. Stop? Boulder pauses. Doesn't shrink.

πŸ”οΈ

After 6–12 months: a mountain.

Release it into the sea. It joins your Mountain Range β€” the panorama of every Boulder you've ever grown.

The chill productivity app.

No death mechanic.

Forest punishes you. Focus Friend guilts you. Boulder can't die. Break focus and it just pauses β€” no streak, no shame.

Slow accretion, not pomodoros.

No fixed intervals. Focus for 20 seconds or 4 hours β€” Boulder grows the whole time. Outcome over streaks.

Your Boulder is yours.

Shaped by your focus mix, no two are alike. The signature of your year, as a chunky pixel sculpture.

Open source. Free forever.
