The Daily Habits App is a mobile application we developed to help users build and track their daily habits, fostering personal growth and productivity. Built with React Native and Expo, the app provides a cross-platform solution that works seamlessly on both iOS and Android devices. We chose React Native for its ability to deliver a native-like experience while allowing us to maintain a single codebase, which significantly reduced development time.

Firebase serves as the backend for the app, handling user authentication, data storage, and real-time updates. Users can sign up or log in using their email or social media accounts, with Firebase Authentication ensuring a secure and streamlined process. The app stores habit data in Firebase Firestore, allowing users to create, edit, and track their habits, such as drinking water, exercising, or reading, with daily check-ins that sync across devices in real time.

A core feature of the Daily Habits App is its habit tracking system, where users can set goals (e.g., exercise 5 times a week) and mark their progress each day. We integrated Chart.js to visualize habit completion rates over time, displaying progress in the form of line charts and bar graphs. This visual feedback motivates users to stay consistent and identify patterns in their behavior, such as which habits they struggle with most.

The app also includes reminders and notifications to prompt users to complete their habits at specific times of the day, a feature we implemented using Expo’s notification API. Additionally, we added a streak system to gamify the experience—users earn badges for maintaining streaks, such as completing a habit for 7 days in a row. Since its release, the Daily Habits App has helped thousands of users build better routines, with an average user retention rate of 60% after 30 days.
