Leern.ai Mobile App Development
Budget: $250 – $750 USD
Updated Leern.ai Mobile App Development Proposal
Project Overview
Project Name: Leern.ai
Objective: Develop a fully functional cross-platform mobile application for iOS and Android using Flutter, with complete frontend implementation as per the Figma design, fully integrated with the existing backend REST API.
Budget: $650 (fixed)
Deadline: No hard deadline; early release preferred.
Team: To be executed by a single developer or small team within budget constraints.
Technical Overview
Frontend:
Framework: Flutter (Dart) for cross-platform development.
State Management: To be finalized at project start. Options include:
Bloc: For complex state management and scalability.
Provider: For simpler state management with less boilerplate.
Riverpod: A modern alternative to Provider with better dependency injection.
Recommendation: With the updated budget, Provider is still recommended for its simplicity and faster implementation, but we can consider Riverpod if the app requires more advanced state management (e.g., for handling dynamic data updates). This can be finalized at the project start.
UI Design: Implement the provided Figma design (link: Figma Design). The design includes a comprehensive set of screens:
Authentication (login, signup, password recovery).
Home screen with lesson categories and search.
Lesson details, progress tracking, and interactive content.
User profile, achievements, and settings.
Notifications, progress charts, and additional features as shown.
Backend:
In active development.
A significant portion of the REST API is already implemented.
The developer will integrate the Flutter app with the API for all features, including user authentication, lesson retrieval, progress tracking, profile management, notifications, and settings.
Scope of Work
The entire application will include the following:
User Authentication:
Login, signup, and password recovery screens with form validation.
Secure API integration for authentication.
Home Screen:
Display lesson categories, featured lessons, and user progress.
Search functionality for lessons.
Lessons:
List of lessons with filtering and sorting options.
Lesson details screen with content (text, images, etc.).
Progress tracking for each lesson (e.g., completion percentage, stats).
Profile Management:
User profile with editable details (name, email, etc.).
Display learning stats, achievements, and history.
Settings:
App settings (language, notifications, theme).
Logout functionality.
Additional Features (as per Figma):
Notifications screen (fetch and display notifications via API).
Progress charts and detailed stats (e.g., bar charts, line graphs).
Interactive elements like buttons, toggles, modals, and pop-ups.
Navigation:
Bottom navigation bar for main sections (Home, Lessons, Profile, Settings).
Smooth transitions and navigation between screens.
Out of Scope (due to budget constraints):
Backend development (assumed to be handled separately).
App store deployment (can be discussed as a separate phase).
Features not explicitly shown in the Figma design (e.g., real-time chat, unless API and design support it).
Development Approach
Setup and Planning (2-3 days):
Set up the Flutter environment and project structure.
Finalize state management (Provider recommended, with Riverpod as an option).
Review the Figma design and map out all screens and API endpoints.
Estimated Cost: $50 (8% of budget).
UI Implementation (8-10 days):
Build all screens as per the Figma design (approximately 30+ screens).
Implement all UI elements, including forms, buttons, charts, and navigation.
Use Flutter’s widget system to create reusable components for efficiency.
Ensure pixel-perfect design implementation with attention to detail.
Estimated Cost: $250 (38% of budget).
API Integration (8-10 days):
Integrate the app with the existing REST API for all features.
Implement user authentication (login, signup, password recovery).
Fetch and display lessons, user progress, profile data, notifications, and settings.
Handle edge cases (e.g., no internet, API errors) with proper user feedback (e.g., loading states, error messages).
Estimated Cost: $200 (31% of budget).
Testing and Bug Fixing (5-7 days):
Test the app on both iOS and Android simulators/devices.
Fix UI inconsistencies, API integration issues, and navigation bugs.
Ensure all features are fully functional, responsive, and polished.
Perform additional testing for edge cases (e.g., slow network, device rotation).
Estimated Cost: $100 (15% of budget).
Final Delivery and Polish (2-3 days):
Add minor UI polish (e.g., transitions, micro-interactions).
Package the app for internal testing (APK for Android, TestFlight for iOS if possible).
Provide source code and detailed documentation for handover.
Estimated Cost: $50 (8% of budget).
Total Estimated Cost: $650
