How every course works
A course that teaches, not a game that nags
Understood In teaches you the language the way a good course does, with the parts that make it stick.
Grammar, explained
Every lesson starts with a real explanation — the why, not just the what — with examples you can play out loud.
Speak from day one
Say each sentence out loud; your phone's speech recognition checks you and shows what it heard. Skip any time.
Type it, don't tap it
Typed answers, word-bank building, listening dictation, fill-in-the-blank, matching and dialogues.
Smart Review
Spaced repetition resurfaces every word you have learned right before you would forget it, plus a Daily Workout of due words and your misses.
Stories & conversations
Graded readers with tap-a-word meanings and audio, and branching conversations where every reply is a choice with feedback.
Taught in your language
Lessons are explained in the language you choose — 33 languages today.
Works offline, no account
The whole course ships inside the app. Your progress stays on your phone; there is nothing to sign up for.
No hearts, no paywalled lessons
Mistakes come back at the end of the lesson until you get them. You are never locked out for trying.
Pricing — every app
Free means free
The free version shows ads: a banner on the Learn and Review screens, and now and then a full-screen ad after you finish a lesson or activity, never during one. Pro removes the ads. That is the only difference, in every Understood In app.
