The lesson is one hour. The week is 167.
Studies on memory say you forget about half of a new lesson within a day — unless you practice. But practice usually means boring drills and word lists. That's the gap we cover. (Yes — that's our name.)
You learned it Monday. By the weekend, it's gone. No practice in between.
A file you do alone, with no hints and no feedback until next week.
You study a lot, but you can't see it. Progress feels like nothing.
We cover the gap between your lessons.
Every exercise levels something up
Grammar, vocabulary, listening — each skill has a level, and every answer moves it. Streaks for showing up, badges for milestones, and gaps shown before they become problems. Your progress stops being a feeling and becomes a map.
Yesterday I to the market.
Your next exercise is built from your last mistakes
Got the past tense wrong twice? The app notices. It explains the rule again — in a new way — and gives you practice on exactly that. Not 20 random exercises. Yours.
Nailed it (90%+)? It skips the easy stuff and moves you forward.
This week for you
Made just for your gaps
Use “saw” for the simple past of “see”. “Seen” needs “have”: I have seen.

Teaching, not learning? For teachers →
Write. Get corrected. Keep the corrections.
Post in the language you're learning. Other learners and teachers mark what to fix — and why. Every correction you accept goes into your own mistake log: a private map of what to practice next.
You can correct others too. Helping someone is the best way to learn yourself.
Real practice with real people — not another quiz.
Last weekend I go went to the beach with my friends. We have had a great time!
Use the past tense for finished actions: go → went, have → had.
