Minimalist day planner PWA. Vertical timeline with drag-to-reschedule, repeating tasks, month calendar, tasks in folders, formatted notes, archive. No accounts, offline-first, optional sync between devices via a single access code (Cloudflare Pages + KV or self-hosted). One HTML file, six languages.

I love that this runs in the browser. Given that downloading and installing an app is a cognitive barrier in itself, lowering the barrier to entry like this is a great approach.

A minor UX observation: the task creation modal feels slightly heavy on information, and supporting drag-to-set time selection would make the experience even smoother.

Best of luck with the project!
