Memorize
Read full descriptionHide full description
Make your own vocabulary flashcards in seconds, then let spaced repetition decide when you see them again. VocabFlash sorts every card into one of five Leitner boxes: miss a word and it returns tomorrow, answer it right and it steps back — 1, 3, 7, 14, then 30 days. That is how words move from "seen once" to remembered for good. No accounts, no classes, no social feed. Just your words, a clean card flip, and a schedule that does the remembering for you. Every grading button tells you exactly what happens next — "Move to Box 2 · review in 3 days" — so you always know where a word stands. WHAT YOU GET • A Daily Review queue holding exactly the cards due today — a focused few-minute session instead of an hour of cramming • Five Leitner boxes with real intervals (1, 3, 7, 14 and 30 days), so hard words come back fast and mastered words step aside • Your own decks of front/back cards — type them in, or paste a comma-separated list and import a whole deck at once • Ready-made starter decks (Business English, Spanish travel phrases, everyday German and more) you can add with one tap • A streak and a 30-day history chart built only from your real reviews, plus a mastery map showing how many cards sit in each box • A daily reminder at the time you choose, so review day never silently slips past PERFECT FOR • Language learners moving new words from a textbook into long-term memory • Students drilling vocabulary for IELTS, GRE, TOEFL or school exams • Professionals memorizing industry terms in a second language • Anyone who keeps forgetting the same words and wants a system, not willpower WHY NOT JUST A LIST IN YOUR NOTES APP? A list shows you everything, every time — you re-read the words you already know and skim past the ones you don't. Leitner boxes flip that: missed words return tomorrow, known words retreat toward next month. Ten well-timed cards a day beat a hundred re-read lines. PRIVATE BY DEFAULT Your decks, cards and study history live on your iPhone. No account, no sign-up, no upload. Export any deck to CSV whenever you want — your words are yours. FULL ACCESS VocabFlash requires Full Access, available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Full Access covers everything: unlimited decks, Leitner spaced-repetition scheduling, daily reminders, CSV import and export, and progress insights. Start tonight: add ten words you keep forgetting, and let the boxes take it from there.

Verdict
The clearest difference is update cadence: LearnKata at fortnightly against Memorize's every 3 months. LearnKata also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
