Start from the Cyrillic alphabet and build to a solid A2. Russio uses spaced repetition and active recall so the words stay in your memory, not just in today's lesson. No streaks, no guilt. Free to start on iOS and Android.


Most apps are great at getting you started and terrible at making it last. Russio is the opposite. Every part of it is tuned for long term memory, all the way to a real A2.
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 is never wasted.
After the first look you produce the answer: type it, say it, trace it. Recognising 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. You are never bored, never buried.
Progress is tied to words you genuinely remember, not to a daily counter. Miss a day and nothing breaks.
A warm, hand illustrated world instead of the usual owl and confetti. 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 Cyrillic letters with tracing, audio, and mnemonics, then blend them 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.
Lock everything in with graded stories and perfectly timed reviews, all the way to a solid, durable A2.
Russio starts you at zero. You trace each of the 33 Cyrillic letters, hear it spoken, and tie it to a memory hook, then immediately blend letters into real words. By the end of your first session you are reading short Russian words on your own.
Yes, Russio is free to start. The full Cyrillic alphabet and the A1 Survival level are free forever. Russio Pro unlocks the A2 to C2 levels, available as a subscription or a one time lifetime purchase.
Russio is built for retention, not for streaks. A real spaced repetition scheduler and active recall make the language stick long term, and missing a day never punishes you. The honest goal is a solid, durable A2, which is exactly where most apps leave learners stranded.
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 shows you each word right before you would forget it. Russio uses a modern FSRS scheduler to time every review, which means you remember more while studying less.
It depends on how often you practise, but Russio is designed to take an absolute beginner from the alphabet to a solid A2 through short daily sessions. 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.
Free to start, fully offline, and calm by design. Download Russio and decode real Cyrillic in your very first lesson.
