71. Tidewatch

Tidewatch started as a weekend experiment and turned into the thing I actually use. It is a surf forecast dashboard, drawn minimal, and deliberately small: one screen, one job, no settings page.

• Responsive down to a phone without a separate layout
• Every action is undoable
• Shareable state — the URL is the document

v0 and Supabase did most of the lifting. I wrote the schema by hand and let the generated components follow it rather than the other way round.

Next up: better empty states, and a proper import path for people arriving with existing data.
