Liftrava
An offline-first fitness PWA that lets lifters log every set with zero signal and builds their training plan from what they actually train.
Built in Application Development
Overview
What we built.
An offline-first fitness PWA for logging workouts anywhere, automatically building training plans from real sessions, generating progression targets, and visualizing muscle recovery.
Project details
How it works.
- Full-stack system spanning four deployed applications, verified through end-to-end testing across offline and slow-network scenarios.
- Works completely offline with an idempotent synchronization process and local replay queue to reliably sync sets upon reconnection.
- Automatically builds adaptive training plans and generates next-session progression targets from the athlete's actual training history.
- Features a 187-exercise library, 3D muscle-recovery mapping, PR tracking, guest logging, and integrated Paddle subscriptions.
