Does Astrophy work without internet?

How is Astrophy different from other astronomy apps?

Unlike stargazing or sky map apps, Astrophy is a structured learning platform — similar to Duolingo but for space science. It offers progressive courses with lessons, quizzes, and XP tracking. It is also one of the few astronomy apps that is completely free, ad-free, and designed specifically for children ages 8-16 with age-adapted content.
