EV (English Vocabulary) is an Android application designed to help users improve English vocabulary through structured learning. Oodles developed the app with features such as flashcards, quizzes, spaced repetition, audio pronunciations, and progress tracking to deliver an engaging and effective language-learning experience.

The objective was to build a scalable, maintainable Android application following modern development practices. Oodles set up the complete development environment, implemented Clean Architecture, and organized the app into modular components. The scope included analytics, ads, reminders, text-to-speech, speech-to-text, progress tracking, and multi-environment build variants to support development, testing, and production releases.

Oodles delivered a robust native Android application built using Clean Architecture and Android’s recommended patterns. The app was structured into well-defined feature and core modules, enabling easy scalability and long-term maintainability. We integrated notifications, analytics, ads, audio-based learning features, and automated CI/CD workflows for testing and deployment. The result was a production-ready vocabulary learning app with a strong technical foundation and a smooth user experience.
