I released Sport Planner, a client-side SPA to design and run training sessions for martial arts, fitness classes or any sport where a reusable drill catalogue and a live schedule are useful.
It grew out of my own kung-fu teaching workflow. I wanted the next session ready on mobile, easy catalog maintenance and backups one click away.
The app includes reusable work catalogues, session timeline editing, calendar planning, attendance tracking, mobile-first execution and Supabase sync with JSON backups.
It is built with React, TypeScript, Zustand, React Router, Headless UI, TailwindCSS and Supabase. It keeps an offline-first local state while syncing when the user signs in.
