Merumi turns the time you already spend on your phone into a language you actually speak. ONE LESSON A DAY, IN THREE STEPS Meet new words on flashcards. Prove you know them in a quiz. Then use them in a sentence you write yourself — and an AI tells you what to fix and why, not just whether you were right. Spaced repetition brings every word back just before you would have forgotten it. POINT YOUR CAMERA AT ANYTHING Don't know the word for it? Photograph it. Merumi names it, says it out loud, and files it in your dictionary. LEARN FROM THE VIDEOS YOU ALREADY WATCH Paste a TikTok, Reel or Short — or share it straight into Merumi. You get the transcript with a translation under every line, and you can tap any word to see what it means. Keep the ones worth keeping. PUT A WORD IN FRONT OF THE APPS YOU OPEN TOO OFTEN Entirely optional, and entirely yours to set. Choose the apps. When you open one, a word appears instead, and a short quiz gets you in. Turn it off whenever you like. Merumi never sees which apps you picked — iOS doesn't tell it. WHAT'S INSIDE • Spanish for English speakers, English for Russian speakers • 5,400+ Spanish and 9,800+ English words, graded A1 to C2 • IELTS mode: the complete Academic Word List, in frequency order • Pronunciation on every word • Your own dictionary, synced across your devices • A daily goal you set yourself, and a streak worth keeping MERUMI PREMIUM Merumi is a subscription. It unlocks the daily lesson, the AI sentence exercise, the word scanner, the video breakdown and the app blocker. • Annual — includes a 3-day free trial • Monthly Payment is charged to your Apple Account at confirmation of purchase.

Verdict
The clearest difference is in-app purchases: Eduzer at none against Merumi's 3. Eduzer also leads on iOS requirement (13.0 vs 16.4). Merumi's advantage is update cadence (every 4 days vs every 18 months). On price, ads and device support there is nothing between them.
