Aura Training Club

via Toptal

A cross-platform fitness app bringing programs, workouts, and nutrition together in one place.

Aura Training Club is a cross-platform fitness app that brings programs, workouts, and nutrition together in one place, helping users structure their training and stay consistent. I worked as a full-stack developer across the entire platform, building the React Native / Expo mobile app (iOS & Android) with workout tracking, video-based programs, and offline session sync. I also implemented end-to-end subscription monetization via Apple App Store and Google Play in-app purchases.
