Hanglass is a Korean vocabulary app designed specifically for TOPIK (Test of Proficiency in Korean) preparation.
A common pitfall in vocabulary learning is thinking you've memorized a word — only to forget it later. Hanglass solves this by applying the forgetting curve: the app automatically brings back words right when you're about to forget them, based on your personal learning progress.
Each word is rated as "Known," "Unsure," or "Unknown," and review timing is optimized according to your learning history — helping vocabulary stick in long-term memory, efficiently.
・Focused on high-frequency TOPIK vocabulary
・Smart review system tailored to your recall level
・A sustainable learning cycle you can stick with
Perfect for learners preparing for TOPIK, or anyone who struggles to make Korean vocabulary stick.
