Overview

Workout Book is a personal fitness companion app that helps users log workouts, track nutrition, and monitor long-term progress. Coaches can create and share custom routines with their clients.

The Challenge

The fitness app market is saturated, but most apps are either too simple or too complex. The client wanted a clean, motivating experience that worked for both casual gym-goers and serious athletes.

Our Solution

We built a React Native app with a Node.js backend and Firebase for real-time sync. A custom routine builder lets coaches create structured programmes. Progress charts use D3.js for beautiful, interactive visualisations.
