Discover and learn Japanese with complete, real sentences. 180 themes of 10 sentences each, from the classics to the unexpected — 1,800 sentences in total. Free to download, no account, no ads. ONE SENTENCE AT A TIME Most learning methods drown you in vocabulary lists. Looplingo works differently: one sentence, one context, one score. Every review is rated, and the system prioritizes whatever keeps slipping away. The more you practice, the less time you waste. EVERYDAY THEMES Restaurant, transport, hotel, family… Pick a theme, review its sentences, and track your progress card by card. A fully mastered theme gets validated — but stays replayable anytime. THREE REVIEW MODES • Cards: flip the card and rate yourself honestly. • Multiple choice quiz: pick the right translation out of four options, with visual and haptic feedback. • Priority: a smart session that gathers your difficult sentences and your favorites. SIMPLE, HONEST PROGRESS No black-box algorithm: every correct answer brings a sentence closer to being acquired, every mistake pushes it back. And each direction is tracked separately — understanding a sentence and producing it are two different skills. When a sentence reaches your mastery threshold (adjustable from 1 to 100), it's acquired. Slow memorizer? Raise the threshold. Want to move fast? Lower it. YOUR FAVORITES FIRST Tap the heart on sentences that keep tripping you up. Priority mode puts them at the front of the session, together with the sentences the app automatically detects as fragile. BUILT FOR JAPANESE Display in hiragana or kanji, optional romaji under the cards, and text-to-speech to hear every sentence with the right pronunciation. CONSISTENCY OVER INTENSITY Daily progress rings, streak, daily goal, and an optional daily reminder: five minutes a day beats an hour on Sunday. FREE TO ACTUALLY TRY The free version is not a demo: 4 full themes, all language pairs, and every review mode, with no time limit. LOOPLINGO PRO, ONE-TIME PURCHASE FOR LIFE Unlock 100% of the themes (all 180, 1,800 sentences), add your own custom sentence packs (JSON, loaded from a simple URL), and export or restore your database anytime. One single purchase, no subscription. Your data stays on your device, and deleting a pack never deletes your learning history. 5 LANGUAGES, EVERY COMBINATION French, Japanese, English, Chinese and Korean are all built in — and every pair works both ways: French → Japanese, Japanese → French, Chinese → Korean, English → Chinese… Learn in whichever direction you want, from whichever language you already speak. More languages are on the way — feel free to tell us which ones you'd like to see first. Open a theme. Flip a card. Come back every day. That's the whole secret.
