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. FREE FOREVER (A1–A2) - 1,700+ essential Estonian words (CEFR levels A1–A2) - Real example sentences for every word, sourced from the EKI corpus - Native pronunciation by the Mari voice (TartuNLP / University of Tartu) - Full Estonian grammar built into every card — all 14 noun cases, verb conjugations, every form - Your own memory hints on any word - Learn through English, Ukrainian or Russian - Smart spaced repetition that adapts to how well you remember - Works offline. No account. No ads. No tracking. B1 LEVEL (OPTIONAL ONE-TIME PURCHASE) - 2,741 new B1-level words with examples, word forms, and audio - Didactic order — greetings and core verbs first, not raw frequency - Switch freely between A1–A2 and B1 tracks on the home screen - Cloud sync via Sign in with Apple or Google — protect your progress and restore it on any device - Cloud sync protects your associations too, and exports them to CSV (word / translation / level / hint) A1–A2 stays free forever. B1 is a single purchase — no subscription. DESIGNED FOR REAL LEARNING - Clean, distraction-free interface — a calm space to focus - Honest self-rating: Again / Hard / Good / Easy - See your progress: streak counter and words learned - One tap reveals the full grammar of any word — all cases and forms in one place - Beautiful typography, light and dark themes PERFECT FOR - Russian speakers living in or moving to Estonia - Expats and newcomers learning Eesti keel - Ukrainians settling in Estonia - Anyone who wants Estonian done right, without the busywork Estonian is hard — the cases, the forms, the unfamiliar words.
