Duolingo is holding its annual Duocon event today to show off some of what it’s working on. One of the big things the company has in the pipeline is an app called Duolingo Math, which marks its first move outside of language learning.

The app has two main elements. The first is a math course designed for elementary school-level kids. As you’d expect if you’ve used the main app, Duolingo will offer short, gamified math lessons. The app also has a brain training component geared toward those aged 13 and older. The idea is to help you improve your math and everyday thinking skills. 

Meanwhile, Duolingo is set to add another language course. This time it’s for Zulu, which is the most widely spoken first language in South Africa. Duolingo said the introduction of the Zulu course is part of its efforts to increase cultural awareness of lesser-studied and endangered languages.

In addition, the company will offer a look at a redesign for Duolingo ABC, a literacy app for kids. Duocon will also include details on some upcoming social features. One of those is called Friends Quest. Duolingo says it hopes to help folks have more fun while they work toward their language learning goals.
