Gymco on iPhone: Train, Today and Add food

Overview

Gymco is a diet and training app for people who lift. It puts food logging, training plans and progress in one place. Targets adapt to what you actually eat and weigh, and the streak rewards showing up, never eating less.

The project covers the whole product: an iOS and Android app, a three-language website (English, Arabic, Spanish), and the Control Center, where the team runs features, content, prices, releases and the website without a deploy.
