The Challenge

Having an awesome app that has gained so much traction, one challenge that Plain Vanilla Games faces is how to keep that growth. To continue growing its user-base at a fast pace, expanding into international markets is the strategy to go and localization becomes a crucial part in reaching out to users whose first language is not English.

To attract more international users, other than app description and in-app text, Plain Vanilla Games also needs to keep the QuizUp website and help-desk articles multilingual to ensure the smoothest user-experience. As these contents are all written in different file formats and stored on different platforms, what Plain Vanilla Games needs is a solution that can help them manage the localization process efficiently. Especially with their agile development environment, managing frequent incremental updates can be really cumbersome without a good tool in place.

Since questions inside the QuizUp app are all contributed by users, Plain Vanilla Games also wants to include their users in the localization process where users can suggest, vote for and review translations. So they needs a solution that the provides the option to combine professional translation service and crowdsourced translation so that they can rely on professionals for the core app UI and help documents while engaging users in localizing the questions.
