Full description
Learn Japanese every day, without even opening an app. Most language apps only work when you remember to open them. Kotoba Loop is different. It puts a new Japanese word right on your home screen, so you learn in the small moments you already have: waiting for coffee, checking the time, unlocking your phone. Words at a glance, effortlessly. Words at a glance: Add the Kotoba Loop widget and a fresh word greets you every morning: kanji, reading (furigana), and meaning at a glance. It blends into your home screen with themes that match your style and refreshes on your schedule. No streak guilt, no nagging notifications. Just Japanese, quietly becoming part of your day. See what you want to see: Every word is graded by JLPT level, from N5 all the way to N1. Whether you're learning your first hundred words or polishing advanced vocabulary before the exam, you're always studying what matters for where you are. Remember what you learn: Seeing a word once isn't enough. Kotoba Loop's built-in review system uses spaced repetition to bring words back at just the right moment, right before you'd forget them. Mark each word as new, learning, or known, and let the app handle the schedule. No giant decks, no cramming, no burnout. Real words, real context: Every entry includes kanji, furigana readings, clear meanings, and natural example sentences that show how a word is actually used. Browse and search the full dictionary any time you're curious. Beautiful, everyday: Calm typography, thoughtful themes, and full light and dark mode. Kotoba Loop is an app you'll actually want on your home screen. Yours, and only yours: Kotoba Loop works completely offline. No account to create, nothing to sign in to, and your progress stays on your device. Back it up and restore it whenever you like. Free to start, yours to keep: Kotoba Loop is free with the complete N5 level, the full review system, every theme, and the home-screen widget. Unlock Kotoba Loop Pro once to open up N4, N3, N2, and N1 vocabulary, custom daily study limits, and faster word refresh. One simple purchase. No subscription, ever. Add the widget today, and let Japanese find you.
