Kahoot has launched a mobile app that is designed to make homework fun and more social.

Oslo, Norway-based Kahoot started in 2013, creating online quiz games for schools with an educational focus. Now the web version has 50 million monthly active users, and it is launching its brand new mobile app on iOS and Android. The idea is to bring the magic of game-based learning outside of classrooms, allowing teachers to send after-class challenges to students as homework assignments.

You can play it as a single player trivia game, or you can challenge your friends and family. The trivia quizzes can cover just about any topic that a player is interested in. The mobile app will cater to students who are spending an increasing amount of time on their mobile devices, giving them an opportunity to review educational material outside the classroom through gamification.

“Teachers and students love playing Kahoot and don’t want to stop when the bell rings,” said Erik Harrell, CEO of Kahoot, in a statement. “Kahoot! makes learning fun — and now homework, too. We are excited to launch the app after receiving an overwhelmingly positive response from teachers and students post our beta launch in June.”

Kahoot helps reinforce topics that are taught in traditional ways in classrooms or homework. A beta version of the mobile app launched last June, and that has 2 million users.

Kahoot is also relaunching its Kahoot Studio, which offers free, ready-to-play curriculum-aligned original games covering a range of subjects. The app isn’t just for teachers and students. Anyone can play on the mobile app, which has access to a library of more than 20 million public Kahoot quizzes.

“Having beta tested the new Kahoot app, I can confidently say that teachers are going to love having the ability to assign Kahoots as homework”, said Matthew Castilleja, instructional technology specialist at Round Rock Independent School District in Round Rock, Texas, in a statement. “This will encourage students to review educational material and take learning outside the classroom walls, all in a fun and engaging way. I can see teachers and students using Kahoot a lot more by being able to play Kahoot and learn on the go.”

The company has 54 employees and it has raised $26.5 million to date from investors including Microsoft, Creandum, and Northzone.
