CatyFlash: Learn Estonian
Flashcards curated by experts
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Learn Estonian the smart way — with flashcards built on real linguistic data, not random user uploads.
CatyFlash uses spaced repetition (the proven FSRS algorithm) to move words from "just saw it" to "know it for life." You review each word exactly when you're about to forget it — so 15 minutes a day actually sticks.
Available in English, Russian, and Ukrainian — learn Estonian through whichever language you know best.
WHY CATYFLASH IS DIFFERENT
Most flashcard apps hand you an empty box and say "make your own deck." Then you drown in other people's typos, bad translations, and missing grammar. Learning from messy cards is harder, not easier.
We took the opposite approach. Every word, translation, and example sentence in CatyFlash is curated from the Institute of the Estonian Language (EKI) — the official authority on Estonian. No guesswork. No clutter. Just open the app and learn.
MAKE EACH WORD YOUR OWN
A textbook mnemonic almost never sticks — it's someone else's joke for someone else's brain. The hint that works is the one you invent. So CatyFlash lets you attach your own memory hint to any word: a sound-alike, a mental image, a link to a word you already know.
Tap the pencil, write your association, done. A small "eye" keeps it hidden until you choose to peek — so it never spoils an honest review. A fine thread visually ties each hint to its word. Edit or delete anytime.
This is the part most apps skip, and it's the part that does the real work. Free on every level, A1–A2 included — no paywall on your own memory.
