Hanase turns the in-between moments of your day into study time. A flash card arrives as a notification on your Mac, iPhone, or Apple Watch. You glance, you guess — and one tap reveals the answer. A little, often, until it's yours. WHY HANASE IS DIFFERENT • Built around notifications, not sessions. There's no "study time" to schedule. Cards find you while you're already looking at your devices. • Works everywhere your Apple devices already work. Native apps for macOS, iPhone, iPad, and Apple Watch. Widgets on every platform. Settings sync via iCloud. • Local-first. No accounts, no analytics, no profile data. Your settings sync between your own devices through iCloud — that's it. • Beautiful by default. Bundled Newsreader and Noto Serif JP typefaces. Real typography, not stock system fonts. HOW IT WORKS 1. Pick a pack — Japanese (JLPT N5 and N4) ships bundled free, and beginner Spanish, French, and German are free too. 2. Set the rhythm — every 20 minutes, every hour, only during work hours, never during quiet hours. 3. Tap notifications throughout the day. A glance, a guess, a reveal. The widget on your home screen and watch face always shows your latest card. WHAT'S INCLUDED • A free beginner tier in four languages — JLPT N5 + N4 Japanese (300 cards, bundled on first launch) plus beginner Spanish, French, and German • A growing catalog of premium packs ($0.99 to $2.99) — every JLPT level and all 2,136 jōyō kanji, Spanish/French/German up to B2, French cooking vocabulary, HTTP status codes, and more • Widgets for iPhone, iPad, Mac, and Apple Watch — large, small, and lock-screen sized • Favorites system across all your devices • Quiet hours and pause controls when you don't want interruptions PRIVACY Hanase has no servers and no account.
