Mobile App
Coach
A personal accountability fitness app focused on simplicity, accountability, and consistency. No feature overload.
The Client
About this project
Coach is a private, iPhone-only fitness accountability app built for personal use. It was also the first mobile app project completed by the developer. The app focuses on simplicity, accountability, and consistency, rather than feature overload.
The Challenge
What we were up against
Mainstream fitness apps were overly complex with too many features
Poor alignment with personal routines and goals
Lacking real accountability mechanisms
Too much decision fatigue around what to track
The goal was to build a tool that enforced daily discipline with minimal friction
The Solution
What we built to solve it
Personalised Daily Accountability System
Coach creates a personalised daily plan based on onboarding inputs: daily step target, gym time goal, gym location (GPS-pinned), weight, height, activity level, and calorie targets. Each day revolves around three core tasks: step goal, gym attendance (location-locked), and meal logging. Completing all tasks completes the day's streak.
Key Features
- GPS-locked gym time tracking
- Apple HealthKit step sync
- Run & walk tracking with maps
- Simple meal logging (MyFitnessPal-style)
- End-of-day accountability sharing
- Streak-based motivation system
