Learn English through short cartoon stories
Watch stories of up to 30 seconds, tap the words you don't know and review them with flashcards. No sign-up.
What it is and who it's for
Mumbloo is a set of short stories with cartoon characters, told in simple English. Each story is one everyday scene: a bus, a café, a plane, a doctor's visit.
If you're just starting
Stories use simple everyday English and are mostly at A1 level. Tap any word and see the translation right away.
If you're stuck on the basics
You meet words and phrases in a scene with characters, not in a list. Later they come back as flashcards.
If you're short on time
One story takes under a minute. In settings you can set a goal of 1, 3 or 5 stories a day.
How it works
Watch, tap, save, review.
