Mobile App Development Project (Flutter for iOS & Android) – Full Scope (A-Z)

Project Overview:

I'm looking for an experienced Flutter developer to build a simple mobile app for both iOS and Android platforms. The app will utilize AI technologies, integrating APIs like OpenAI and/or Google Gemini to deliver detailed and insightful information about food based on user-provided images and pre-defined prompts.

App Functionality:

- User Registration and Authentication: Secure and easy user registration/login via email, Google, Apple ID.

- Photo Upload/Capture: Allow users to either capture new photos using the app camera or upload existing images from their device gallery.

- AI-powered Analysis: Upon photo upload/capture, images will be processed through integrated AI APIs (OpenAI, Google Gemini).

- Prompt-based Response: AI analysis will use a predefined prompt to generate detailed information related to the uploaded photo content, specifically focused on food items.

- Display and Interaction: The app will present AI-generated results clearly and engagingly, including text descriptions and optional visual representations (suggestions to be discussed).

- Payments Integration: The app should support in-app subscriptions via iOS google play payment processing.

Deliverables:

- Initial UX/UI design including mock-ups and graphics.
- Development of the complete application frontend and backend in Flutter.
- Full integration with OpenAI and Google Gemini APIs.
- Implementation of secure user authentication and profile management.
- Testing across both iOS and Android, ensuring smooth performance and minimal bugs.
- Assistance and documentation for successfully launching the app on both Google Play Store and Apple App Store.
- Ongoing support for initial bug fixes and post-launch optimizations.
- Detailed technical documentation and source code provided at the completion of the project.

Additional Requirements:

- Initial version will be developed in English (eventually in the language found on the pictures)
- Hosting will be provided by us, but freelancer must provide support and guidance for setup and initial maintenance.
- Complete intellectual property rights and ownership will transfer fully to us upon project completion.

- Experience with RESTful API integrations, specifically OpenAI and Google AI models.
- Familiarity with image processing and handling within mobile apps.
