About this app

Learn Russian from absolute zero to a solid A2, and actually make it stick.

Most apps hand you Russian words and leave you there. But Russian does not work by putting words in a row: every noun changes its ending depending on the job it does in the sentence, most verbs come in two versions depending on whether you finished the thing, and going somewhere on foot uses a different verb from going by car. That is where beginners stall, and it is the part almost every app skips.

Russio drills it.

FREE TO START
The Cyrillic alphabet and the whole A1 level are free, forever. Learn to read, write and produce your first hundreds of Russian words at your own pace, with no time limit.

THE ALPHABET FIRST
Every path starts with the Russian alphabet. Stroke-guided letter reveals, finger tracing and produce-from-memory recall mean you genuinely know each letter and its sound before you move on. No skipping.

THE CASES, PRACTISED AND NOT JUST EXPLAINED
Over a thousand sentence drills covering accusative, genitive, dative, instrumental and prepositional, plus perfective and imperfective pairs, verbs of motion, past and future, negation, comparatives, questions and reflexive verbs. A short card explains the rule once. Then you meet that same rule again and again in sentences you have never seen, until choosing the ending stops being a decision.

NEVER A SENTENCE YOU CANNOT READ
No drill ever contains a word you have not already learned. The single new thing on the screen is the grammar being taught, so you are always working just past what you know instead of guessing.

BUILT TO REMEMBER
A spaced-repetition engine schedules every letter, word and pattern for the moment you are about to forget it. Review the right things on the right day and Russian vocabulary stays in long-term memory.

PRODUCE, DON'T JUST TAP
Active recall by default: you build the answer, you do not pick it from a list. That is the difference between recognising Russian and being able to use it.

AUDIO FOR EVERY WORD
Clear audio for every letter and every word, with the stress marked, so you hear where the emphasis really falls from day one. Works fully offline.

RUSSIO PRO
Opens A2 to C2: 1,800 more words, the full grammar course with the cases finally made clear, every sentence drill, and 70+ graded reader stories with tap to translate. One Pro purchase, your choice of monthly, annual, or a one-time lifetime you own forever.

NO STREAKS, NO GUILT
Miss a day and nothing punishes you. Your reviews simply reschedule. Progress is measured by what you actually remember, not by a counter.

Whether you want to read the Russian alphabet, study Russian for beginners, build vocabulary, or finally understand the cases, Russio is the calm, focused way to learn Russian.

What’s new

Fixed a mix-up in the Reading section: the word МАТ played the sound of МАТЬ (mother) and showed her picture. МАТ now has its own recording.
