Calisthenics Progression

A full-stack calisthenics workout tracker — built for learning purposes. Handcrafted in 2019 with inspiration from Flask Mega Tutorial, now enhanced with the assistance of AI.

Log your training sessions, define custom exercises with progression levels and workout templates, follow your progress in charts, and connect with other athletes. Originally a Flask/Jinja2 monolith, the project is now a Flask REST API + Next.js web + Expo (React Native) mobile architecture with Supabase Auth.
