Learn Korean and French from the ground up. Start with grammar, then build vocabulary that sticks past a streak. Ludus teaches you how the language actually works: how Hangul letters build into syllables, how sentences fit together, and why the rules are what they are. Join 2,000+ learners mastering language, one lesson at a time. Stadiums We breaks lesson units down into stadiums, structured paths that take you from your first letters and sounds, step by step. Each stadium is a short run of lessons and activities that builds on the last, so you always know what you've learned and what comes next. Read Hangul New to Korean? Start with the alphabet. Lessons break down consonants and vowels and show how they combine into syllable blocks, and our Character Stroke game lets you practice writing each letter. With regular practice, you can start reading Hangul within two weeks! Understand the language Stop learning random vocabulary that doesn't appear in daily life. Lessons teach foundations and grammar concepts, so you know why something is right instead of guessing. You build real structure first, then add vocabulary on top. Discover 1M+ premade flashcards Search through our built-in dictionaries, read definitions, and save any word in one tap. Saved words join your daily review automatically, so you spend your time learning instead of making flashcards or remaking sets. Reviews are scheduled with FSRS, a spaced-repetition algorithm that adapts to how well you recall each word. Words surface right before you forget them. Games Play live multiplayer games in the classroom, or play solo Gravity and destroy vocab asteroids before they reach the bottom of your screen. There is a way to study for every kind of learner.

Verdict

The call

The clearest difference is ads: Ludus at none against Idly's shown. Ludus also leads on ratings volume (204 vs 4). Idly's advantage is review sentiment (100% vs 79%) and update cadence (every 3 days vs weekly). On price, rating, in-app purchases and monetization model there is nothing between them.
