gymtracker_

Personal gym tracker with progressive overload detection. Mobile-first PWA, dark or light.

One click deploys the app, provisions a Neon Postgres database, and applies the schema automatically. Just set a 4-digit PIN when prompted.

Demo PIN: 0000 -- try it on the live deployment. Deploy your own copy for a private instance with your own PIN.
