Duolingo is perhaps one of the most popular apps for learning a new language available on the iOS and iPadOS platforms, and despite this fact, the app appears to lack the types of fun and quirky Easter eggs that you might come to expect from an app of this caliber.
That’s where a newly released and free jailbreak tweak called AngryDuolingo by iOS developer Idefix2020 comes into play. It makes using the Duolingo app more fun by giving the Home Screen icon some added character as the app accumulates more and more missed notifications.
