They got you talking about Duolingo. That's why they changed it.

Duolingo keeps doing mass layoffs, so the bird is overworked. You can help him out by switching to a language learning app that actually helps you learn a language instead of endlessly throwing flash cards at you without teaching you anything! Win win.

Attention grabbing apparently.

It's my fault, y'all. I'm sorry.

I recently started using Duolingo to learn Spanish, and it's clinically proven I ruin everything I touch, so I think I'm killing the bird...

Oh, I thought it's because I stopped opening it daily and broke my streaks lol

This is the old duolingo icon

Duo has lost all will to live now that his landscape of progress is a single, non-branching path.

It must feed on the blood of oppressed immigrants trying to learn English or it's immortality will cease

It says it right there. He's 4+ years old.

Not just you, it's the same on Android. Maybe related to April Fools?

Duolingo became old cuz everyone forgot about them. Tragic ;-;

Duo está cansado y viejo.

I love how (apart from endless commentary on apples) the main thing it likes to focus on first is all about what trabajo does to you.

I'm tired, boss. Tired of bein' on the the app store, wantin' to be lonely as an owl in the rain. I'm tired of always havin' people annoying me, tellin' me to give them new words. Mostly, I'm tired of people never memorizin' the vocabulary. I mean, how many times can I give you "Cómo estás?" before you finally remember what it means, Cletus?

There's too much misremembered - it's like pieces of glass in my head, all the time, I've fed you the entire Spanish lexicon ten times, and you've learned three words. Can you understand?

They change it all the time for funsies

They recently added some unlockable graphics for the widget. Nothing major.

Guess they changed the icon just for the hell of it while they were at it.

Time is the real enemy.

They change their icon all the time for laughs along with making amusing videos that exploit the memes

It’s freaking tired of reminding everyone to practice, yet very few people do it regularly
