Start with the Cyrillic alphabet and keep climbing: grammar at every CEFR level from A1 to C2, over 6,000 words, and graded stories to read. Russio uses spaced repetition and active recall to help what you learn stay with you long after today's lesson. No streaks, no guilt. Free to download on iOS and Android, with in-app purchases.
Pick the language you already speak. Every lesson, hint, and translation follows in it, from your first letter to C2.
Starting a language is the easy part. Keeping it is harder, so every part of Russio is built around long-term memory, from your very first letter to C2 grammar.
Trace every letter, hear it, and tie it to a sound with a memory hook. You decode your first real Russian words inside the first lesson.
A modern FSRS scheduler brings each word back at the moment you are about to forget it, so your review time goes to what is slipping, not to what you already know well.
After the first look, you mostly produce the answer yourself: you type it, build it or trace it. Recognizing a flashcard is not the same as knowing it.
Short stories tuned to your level, where you tap any word to translate. Reading is where vocabulary turns into real comprehension.
Russio speeds up when you are flying and adds scaffolding when you slip, so the pace follows how you are doing.
Progress is tied to words you genuinely remember, not to a daily counter. Miss a day and nothing breaks.
A warm, illustrated world, where every screen has one clear thing to do.
Words learned, locked in, and reviewed, at a glance.
From Survival to Mastery, tap any word to translate.
Every letter and word you learn, kept in one place.
Meet the 33 letters of the Russian alphabet: trace each one, hear how it sounds and anchor it with a memory hook, then blend the letters into your first real Russian words.
Produce words from memory, guided by spaced repetition and comprehensible input, so you only ever meet one new thing at a time.
Read graded stories at your level, and let reviews timed to your memory bring each word back, from your first letter up to C2.
With Russio you start at zero. You trace each of the Russian alphabet's 33 letters, hear it spoken, and tie it to a memory hook, then immediately blend letters into real words. By the end of your first lesson you are reading short Russian words on your own.
Yes, Russio is free to start. The full Russian alphabet and the A1 Survival level are free. Russio Pro unlocks the A2 to C2 levels, available as a subscription or a one-time purchase.
Russio is built around memory, not streaks. A spaced repetition algorithm (FSRS) plans every review, you produce most answers instead of picking them, and missing a day never punishes you. The course runs from the Cyrillic alphabet to C2, with grammar at every level.
Yes. Your lessons, the spaced repetition scheduler, and all of your progress run on your device, so you can learn on a plane or underground with no connection.
Spaced repetition brings each word back just as you are likely to start forgetting it, and each time you remember it, the next review comes later. Russio plans every review with FSRS, a modern scheduling algorithm, aiming for the point where you would still recall the word 9 times out of 10.
It depends on how often you practise. A2 is the second of the six CEFR levels, and from there Russio keeps going all the way to C2. There is no fixed deadline and no pressure to rush.
You can learn Russian from English, Italian, Spanish, German, French, Portuguese, Turkish, Polish, Ukrainian, or Chinese. Russian is always the language you are learning.
