Abstract

Gym Grind is an open-source Mobile App Development project. IOS fitness tracking app built with SwiftUI and Supabase. A native iOS fitness tracking app built with SwiftUI and Supabase. Log workouts, track nutrition, monitor body metrics, and visualise your progress — all synced to the cloud. It is built using Swift. Key capabilities include: Authentication — Email/password sign-up and login via Supabase Auth; Onboarding — First-launch flow to set your name, weight unit, and daily calorie goal; Home Dashboard — Daily summary of calories, volume lifted, and weekly sessions. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Mobile App Development mini project or final-year project.

1. Introduction

A native iOS fitness tracking app built with SwiftUI and Supabase. Log workouts, track nutrition, monitor body metrics, and visualise your progress — all synced to the cloud.

2. Objective

iOS fitness tracking app built with SwiftUI and Supabase

This project demonstrates how Swift can be applied to a real-world Mobile App Development problem.

3. Key Features / Modules

  • Authentication — Email/password sign-up and login via Supabase Auth
  • Onboarding — First-launch flow to set your name, weight unit, and daily calorie goal
  • Home Dashboard — Daily summary of calories, volume lifted, and weekly sessions
  • Workout Logging — Create sessions, add exercises, log sets with weight & reps, auto-detect personal records (PRs)
  • Workout Templates — Save and reuse workout templates for faster session creation
  • Nutrition Tracking — Log meals with calories, protein, carbs, and fat; quick-add common foods
  • Body Metrics — Track weight and body fat percentage over time

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which framework is used and why (native vs cross-platform)?
  2. How is app state managed across screens?
  3. Where is the data stored — locally, Firebase or a REST backend?
  4. How are permissions (camera, location, storage) handled?
  5. How would you publish this app to the Play Store / App Store?
