Jiffy - Time Logger & Streak Tracker Android Application

A native Android application designed and developed to help users record productive activities, track habit streaks, and build a long-term repository of personal productivity data. The application combines time logging, streak management, secure user authentication, and cloud-based data storage into a single mobile platform.

This project serves as a practical demonstration of my Android development skills, showcasing my ability to build a complete mobile application using Kotlin, Firebase Authentication, and Firebase Realtime Database.

Project Overview

Jiffy provides users with a simple and reliable way to record how they spend their time and maintain consistency in their habits. Users can create custom activities, log time spent on those activities, and track streaks associated with personal goals and routines.

The application's primary purpose is data collection and persistence. Rather than focusing on analytics and visualization, Jiffy focuses on helping users build an accurate and organized historical record of their productivity. The collected data can later be utilized by external reporting or dashboard systems for deeper analysis.

To support long-term usage and data accessibility, the application integrates Firebase Authentication and Firebase Realtime Database, allowing users to securely access their data across sessions and devices.
