LingoSnap is an AI-powered app designed to help you understand and learn languages naturally. Traveling abroad? Seeing a sign in a language you don’t understand? Take a photo and ask any question in your native language. LingoSnap will not only provide a translation but also explain key vocabulary and grammar concepts while guiding you through pronunciation. Every interaction is saved as a LingoSnap, allowing you to revisit it anytime for review.

LingoSnap is built on Clean Architecture principles to ensure the app is scalable, maintainable, and testable, making it future-proof and easy to evolve. By following this architecture, we achieve a clear separation of concerns, with distinct layers for data, domain, and presentation. This design ensures that the business logic (language learning, translation, etc.) is isolated from the UI, making the app more modular and easier to modify or expand.
The app uses the Model-View-Intent (MVI) pattern for the UI layer. This pattern allows LingoSnap to maintain a unidirectional data flow, ensuring predictable behavior and a more stable and responsive user experience.
- Domain-Centric Design 🧩: All business logic related to language translation, pronunciation, and grammar analysis is encapsulated in the domain layer. The domain layer interacts with data sources (e.g., APIs, local storage) to manage the flow of information, ensuring the UI remains clean and responsive.
- Seamless Integration with Gemini SDK 🤖🌍: The Clean Architecture ensures that the integration with the Gemini SDK (used for natural language processing and AI-powered translation) is seamless and efficient. It powers LingoSnap’s core functionality, delivering high-quality learning experiences.
LingoSnap is developed using modern technologies to ensure high performance, scalability, and a smooth user experience:
- Kotlin 💻: The primary programming language for Android development, chosen for its expressiveness, safety features, and compatibility with modern libraries.
- Jetpack Compose 🎨: A declarative UI toolkit for building user interfaces. It makes UI development simpler and faster while offering flexibility in designing interactive, dynamic layouts.
- Gemini SDK 🤖: The AI engine behind the app, providing advanced translation capabilities, pronunciation analysis, and context-sensitive feedback. It powers LingoSnap’s core functionality, delivering high-quality learning experiences.
- Firestore 🔥: A real-time database that stores user-generated content (like questions, answers, and learning insights). Firestore enables smooth syncing across devices and fast access to data.
- Firestorage 📸: Manages the storage of images uploaded by users (e.g., snapshots of text, hand-written notes, or objects), allowing LingoSnap to provide translations or language learning insights based on the content in these images.
- Coroutines ⏱️: Kotlin’s asynchronous programming tool that helps manage background tasks efficiently. Coroutines allow LingoSnap to perform time-consuming operations (like image processing or API calls) without blocking the main thread, ensuring a smooth user experience.
- Hilt/Dagger 🛠️: Dependency injection frameworks used for managing app components and their dependencies. Hilt ensures that modules are decoupled and scalable.
- Retrofit 🌐: Used for API interactions, particularly with external services that provide language data, translations, or other learning resources.
- Coil 🎨: An image loading library for handling image display, especially for the photos that users upload. Coil ensures efficient image loading and caching, helping the app maintain high performance.
- Room Database 🗄️: A local database solution for caching and storing user data, which allows LingoSnap to work offline and ensure that progress and insights are not lost when the user is disconnected.
🍫 Brownie: Jetpack Compose UI Library 🚀
LingoSnap leverages Brownie to streamline UI development using pre-built components and best practices. Brownie facilitates state management and provides a consistent, flexible UI design, which is perfect for applications like LingoSnap, where a smooth user experience is essential.
- Pre-defined Components: Brownie provides a set of ready-to-use UI components, such as buttons, lists, and cards. These components ensure a consistent and polished visual design, reducing the amount of time needed to create screens.
- State Management: Brownie supports MVI or MVVM architecture, helping manage the UI state in a clean and reactive manner, which is crucial for apps like LingoSnap that involve real-time data and user interaction.
- Customization: Components can be easily customized to fit LingoSnap's visual style, ensuring that the app's UI remains unique and in line with its branding.
- Jetpack Compose Compatibility: Brownie components are fully integrated with Jetpack Compose, providing a smooth development experience and ensuring optimal performance.
Brownie promotes the use of MVI for effective screen state management. In this architecture:
- Model: Represents the current state of the UI. Brownie’s
BrownieViewModelhandles and manages this state, providing it to the UI components in a reactive way. - View: Renders the user interface based on the state provided by the ViewModel. Brownie components seamlessly integrate with Jetpack Compose for smooth and dynamic UI rendering.
- Intent: Represents the actions or events that the user performs (e.g., asking for a translation, uploading a photo). These intents trigger state updates and initiate actions in the app.
