Sanasto

Build your Finnish vocabulary the smart way — by learning the words you'll actually use, in the order that matters most.

Sanasto is a focused vocabulary trainer built on one simple idea: not all words are equally useful. Every one of its 7,300+ Finnish words is ranked by real-world usefulness and tagged with an estimated CEFR level (A1–C1), so you spend your time on high-impact words instead of memorizing rare ones.

HOW MANY WORDS DO YOU KNOW?
Sanasto answers the question most apps can't. Take Sanatesti, an adaptive test powered by a machine-learning estimate: it samples words across the whole difficulty range, adapts to every answer, and estimates the size of your active Finnish vocabulary in just a few minutes. Prefer to track it yourself? Simply mark words as known as you go — search any word and set its status in a single tap.

LEARN WITH SMART FLASHCARDS
• Clean, distraction-free cards showing the Finnish word, its part of speech, CEFR level, and usefulness rank
• Flip any card for instant translations in English and Russian
• Tap "I know it" to move on, or keep practicing

TWO WAYS TO REVIEW
• Learning mode — focus on the fresh words you haven't mastered yet
• Queue (sweep) mode — cycle through your entire list so nothing slips through the cracks

CHOOSE YOUR LEVEL
Words are organized into three levels — Basic, Intermediate and Advanced. Study one level at a time, or review them all together. You decide how far you want to go.
