❗Note: Expo notifications require a development build on a real device (not Expo Go) starting from Expo SDK 53.
📲 So I built the APK file using
eas build --profile preview --platform androidto help you properly test the app, including notification features.
📥 Install the fully functional My Task App directly from the official Expo preview link-Download APK for My Task App
My Task is a lightweight, clean, and user-friendly task management mobile application designed especially for gig workers and busy individuals. It enables users to stay organized by managing their tasks with ease—allowing the creation, editing, deletion, and filtering of tasks based on completion status and priority levels. Built with React Native using Expo, the app uses Firebase Authentication and Firestore for a reliable backend, and follows clean architecture for scalable development.
Follow these steps to get started with development or testing on your device:
- Node.js (v18 or above recommended)
- Yarn or npm
- Expo CLI (
npm install -g expo-cli) - A Firebase Project
- A real Android/iOS device (for local push notifications using Expo SDK 53+)
- Clone this repo
git clone https://github.com/CoderAyushman/my-task.git cd my-task
yarn install
# or
npm installexpo startUse expo-dev-client or run a development build via:
eas build --profile development --platform android
- Email/password registration and login via Firebase
- Appropriate error handling and validation feedback for user inputs
- Add tasks with title, description, due date, and priority (Low / Medium / High)
- Edit tasks anytime
- Delete tasks with confirmation
- Mark tasks as complete/incomplete with a visual indicator (e.g., color or style change)
- All task data is stored securely in Firebase Firestore
- Ensures data persistence even if the app is deleted or reinstalled
- Avoids the limitations of local-only storage like
AsyncStorage, which loses data on uninstall - Real-time updates and syncing across devices (if multi-device support is added in the future)
- Filter task list by priority (Low, Medium, High)
- Toggle view between completed and incomplete tasks
- All tasks are sorted by due date automatically for better planning
- When a new task is created, the app schedules a local notification as a reminder
- Notifications include task title and a helpful message (e.g., "Reminder: Finish [Task Name]!")
- Note: Notifications only work in development builds due to Expo SDK 53+
- ✨ Dynamic Notification Scheduling: Each task automatically schedules a local notification to remind the user after a set time (e.g., 5 minutes).
- 🧹 Notification Cleanup (Bonus): If a task is marked complete before the reminder triggers, the app attempts to cancel the scheduled notification.
- 📱 UI Responsiveness: Designed using
Dimensionsand%based layout to ensure it looks good on both small and large screen devices. - 🧩 Separation of Concerns: Logic is split across
features,core, andappfolders, keeping UI and data responsibilities distinct and maintainable. - 🔍 Expo Router is used for file-based navigation, while logic-heavy components are decoupled and stored in external
features/directory.
- 🔐 Expo SDK 53 Notification Limitation: One of the major challenges was implementing local push notifications using Expo's
expo-notificationsmodule. With SDK 53, notifications are not supported in the default Expo Go app. To overcome this, I created a development build usingexpo-dev-client, which allowed me to test the notification functionality on a real device.
