Fitness Tracking & Nutrition Coaching App
Our client, a fitness coaching business, wanted a mobile app that let members log workouts and meals while coaches tracked progress and adjusted plans remotely.
The main challenge was building a reliable way to sync workout and nutrition data in real time, support custom training plans per client, and keep coaches and members in sync without manual spreadsheets.
Disconnected tracking tools and manual check-ins were making it hard for coaches to scale beyond a handful of clients.
