Fitness & Workout Tracker is a lightweight, privacy-first app for logging workouts, tracking exercises, and recording body measurements. Designed for athletes, gym-goers, and anyone serious about progress, the app combines an intuitive UI with robust offline-first storage and optional server sync so your data stays safe and available wherever you train.

What this app does

This app helps you plan workouts, record sets/reps/weights, measure progress over time, and maintain a history of body measurements (weight, chest, waist, hips, arms, legs). It focuses on speed, reliability, and simple analytics so you spend more time training and less time logging.

Core Features

Workout Logging - Create, edit, and repeat workouts with custom exercises, sets, reps, rest timers, and notes.
Exercise Library - Built-in exercise templates with options to add custom exercises and tags (compound, isolation, cardio).
Body Measurements - Track weight and circumference measurements; view progress charts and historical entries.
Progress History - View personal bests, one-rep max estimates, and workout history with easy filtering by date or exercise.
Offline Support - Full logging capability without internet; reads and writes to local storage immediately.
Server Sync (Optional) - Secure, encrypted sync to the cloud for backup and multi-device access (opt-in).
Templates & Routines - Save favorite workouts as templates and build multi-week programs.
Export & Backup - Export logs and measurements to CSV for personal backup or analysis.

Tech Features & Implementation

Offline-first Architecture - Local database (SQLite/Room) for instant read/write and conflict-free sync when online.
Efficient Data Sync - Delta sync and background queueing to minimize bandwidth and battery use when syncing to the server.
Clean Code & Modularity - Built with a layered architecture (Repository → Service → UI) for maintainability and easier testing.
Responsive UI - Adaptive layouts for phones and tablets; fast animations and accessible interaction patterns.
Secure Storage - Sensitive data stored encrypted on-device; transport encryption (TLS) used during server sync.
Lightweight Analytics - Local analytics for personal insights; no tracking or marketing analytics enabled by default.

Privacy & Data

Your health and workout data belong to you. By default the app stores all data locally on your device. Server sync is completely optional and uses encrypted transfers; personal data is never sold or shared for advertising. You can delete your data at any time from the app settings.
