The problem

As the digital landscape evolved, MobiSystems faced a critical challenge: how to transition Oxford’s renowned print dictionaries into a mobile-friendly format without compromising on quality or reliability.

Users demanded instant access, portability, and accuracy, but existing solutions often fell short, especially when it came to pronunciation, synonym discovery, and intuitive search.

Ensuring linguistic precision and reliability in a digital environment.
Meeting the diverse needs of global users across different languages and professions.
Providing offline access and intuitive search capabilities.
