Challenge
One of the key challenges in developing Speakly was ensuring seamless real-time synchronization of user progress across web and mobile platforms. Users needed to switch between devices without losing track of their learned words, exercises, and progress statistics.

Solution
To ensure real-time progress synchronization across web and mobile platforms, we implemented a cloud-based system using a combination of NoSQL databases, WebSockets, and RESTful APIs. A local storage system allows users to continue learning offline, with a conflict resolution algorithm merging data once they reconnect. To improve performance, we used an event-driven architecture with incremental updates instead of full data syncs. This solution enables seamless cross-device transitions, ensuring users never lose their progress while keeping the system scalable and efficient.

Results
As a result, Speakly users can seamlessly switch between web and mobile platforms without losing their learning progress. The real-time synchronization system ensures that words learned, exercises completed, and AI-driven recommendations are always up to date. With offline mode support, users can continue learning even without an internet connection, and their progress syncs automatically when they reconnect. This solution enhances user experience, engagement, and scalability, making Speakly a reliable and efficient language-learning platform.
