Locking features temporarily to hook users in their early usage of the app
User experience
Gamification
In the first hours spent on Duolingo, 2 of the 5 items of the tap bar are locked. This has two goals. First, this is a way to appeal users' curiosity. They will be willing to keep using the app to see what is behind. Also, Duolingo ensures that users do not feel lost in the complexity of the app.
About the app:
