Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

The app interface is now available in English, Japanese, and Chinese as well as Korean. Until now only the lessons themselves were translated, so the menus, settings, and study screens stayed in Korean whatever language you read in. Chapter titles no longer flatten acronyms. SIMD, GPU, AI, and ML display correctly again. Fixed iCloud sync. Reading progress, bookmarks, lab drafts, and recall notes now save to your private iCloud as intended — anything your device kept locally while sync was failing will upload on its own.
