Greenapple Fitness
Android application · University final-year project
An Android app that generates personalised gym workout routines based on the user's body metrics, experience level, and fitness goals. Built as my final-year Computing project at London Metropolitan University.
The Problem
New gym-goers often rely on generic online routines that don't account for their body type, experience, or goals. Without proper guidance, exercises may be performed incorrectly or be counter-productive. Search interest for "best workout" and "mobile app" has steadily increased over the past decade, showing demand for better solutions.
Key Features
- Account creation with secure encoding, connected to Firebase
- Algorithm-generated workouts tailored to beginner, intermediate, or advanced levels
- Swipe-to-replace exercises that don't suit the user
- Per-exercise notes saved to the database
- BMI and macronutrient calculators
- Workout export to device storage for offline access
- Configurable reminders with device notifications
- Metric/imperial unit switching
How It Works
The app collects information about the user's weight, height, gender, age, exercise frequency, and goals (gain, lose, or maintain weight). An algorithm then generates a routine: beginners get more functional strength exercises, while intermediate and advanced users receive structural strength exercises to better target muscle groups. Users can personalise their routine further by swiping away exercises they don't like — each is replaced by a similar alternative.
