Readling — learn Russian by reading books

Ease into Russian one page at a time.
Readling offers two ways to read: books where Russian phrases are gently woven into the English text, or parallel reading with the original and translation side by side.
You choose the mode and how much Russian you want to see.

No cramming. You simply read — and step by step you start to understand Russian in context.

How it works
• Pick a book and a reading mode.
• In immersion mode, Russian phrases are blended into the English text — you read as usual, but every page brings a little more Russian.
• In parallel mode, the original and the translation sit side by side — perfect for comparing and unpacking unfamiliar structures.
• Tap any word you don't know to see its translation instantly.
• Every translated phrase is saved to your personal dictionary and ready to review with flashcards.

Chat with book characters
• Practice Russian for real — message the heroes of your favorite books.
• Each character replies in their own voice, and the app gently corrects you when you slip up and shows you how to say it right.
• Pick your partner's level — from simple phrases to free-flowing speech.
• Real conversation practice without the fear of making mistakes — you learn by talking, not by memorizing.
