Mora

You know "hablar." Then a real conversation demands "hablaríamos" — and you blank. Mora fixes the part of language learning every flashcard app ignores: grammar has forms, and someone has to build cards for all of them. Now it's not you. Type one verb. Mora generates the full conjugation table — every tense, every person — with native-speaker audio on every form, dropped into spaced-repetition flashcards that schedule your reviews automatically. WHY LEARNERS SWITCH TO MORA Anki is powerful — after hours of deck-building, plugins, and audio hunting. Quizlet is fast — and shallow. Verb apps drill conjugations — then forget you tomorrow. Mora is the only flashcard system that understands grammar: it builds the cards, voices the cards, and schedules the cards. You just study. WHAT HAPPENS WHEN YOU ADD A CARD One verb becomes a complete conjugation table — present, past, future, all six persons. Every word, sentence, and verb form gets native audio instantly. Spaced repetition (the same memory science behind Anki) decides exactly when you'll see it again, so it sticks for years, not days. BRING YOUR OLD DECKS WITH YOU Import TXT/CSV from Anki, Quizlet, or spreadsheets. Mora auto-detects your formatting — and then does something your old app never did: detects the words and conjugates them. TRAIN ACTIVE RECALL, NOT RECOGNITION Sentence-completion mode turns vocabulary into fill-in-the-blank grammar practice — the difference between recognizing a word and actually producing it in conversation. MADE FOR Spanish learners drowning in verb tables. Japanese learners who need audio on everything. Anki users tired of being deck-builders. Anyone who wants the studying without the setup. MORA PRO Unlimited decks, unlimited AI conjugations, unlimited audio. $29.99/year — less than one hour with a tutor, for a study system that never forgets what you're about to. Your first conjugation table takes 5 seconds. Try it. Terms and Conditions are available in the app settings and here: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: COSEA at none against Mora's 3. COSEA also leads on iOS requirement (12.0 vs 15.1). Mora's advantage is update cadence (weekly vs every 5 weeks). On price, ads and device support there is nothing between them.
