About Kaku: Japanese Study Notebook
Kaku is a Japanese notebook designed for beginner-to-intermediate learners. Instead of jumping back and forth between a notes app, a dictionary, and a translator, you write in Japanese and all tools appear right where you're working: - Instant dictionary - highlight any word and matching entries appear above the keyboard, with readings, word types, and real example sentences. Powered by an offline dictionary, lookups are instant and work anywhere. - Write with training wheels - stuck on a word? Highlight the English word and insert the Japanese one in one tap, including the conjugated form you need. - Translate your notes - check your sentence structure by translating a whole note into your native language. 20 languages supported. - Read Aloud - Kaku reads your note out loud, highlighting each word as it's spoken, so you can shadow along. Choose from the best Japanese voices on your device. - Scan text with your camera - turn textbook pages, signs, and handwritten notes into editable text using built-in OCR. - Made for focus - a clean, paper-inspired design, folders to organize your study notes, and adjustable text size for comfortable reading. - Private by design - your notes live on your device. Kaku feels at home on iPhone, iPad, and Mac. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
