Satori on your phone
The same focused grammar drills, in your pocket — offline, with a review queue that brings a topic back right before you forget it.
What it looks like
Real screens, not mockups.
What's in it
54 topics, A2–B2
Tenses, nouns and articles, pronouns and determiners, adjectives and adverbs, prepositions — 1,600+ exercises in short sessions of ten.
Every answer explained
Right or wrong, you get one line on why — the same explanations you already get on the site.
Review that remembers for you
Spaced repetition schedules each exercise. The Review tab shows what is due today, across every topic you have touched.
Works offline
Exercises ship inside the app. No account, no sign-up — your progress stays on the device.
Pay once, not monthly
15 topics are free forever. A single purchase opens the rest — not a subscription, and new topics are added to the course at no extra cost.
No streaks to lose
Miss a week and nothing resets. The queue just waits for you.
Nothing to install yet
The exercises are free on the web in the meantime — same topics, same explanations.
