HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (44 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

항상 공부 잘 하고 있습니다 한자 정보를 확인할 때 여러 개의 뜻과 음을 볼 수 있는데 그 중에서 해당 단어의 의미에 맞는 뜻과 음을 표시해 주면 좋을 것 같습니다

★★★★★Mar 27, 2025

시간 날 때 공부하기 참 유용합니다! 테스트를 조금만 더 어렵게하면 실력증진에 도움이 될거같습니다.

★★★★★Mar 9, 2025

미국에서는 이게 다운로드가 않되는거 같은데요 어떻게하면 다운로드해서 공부를 할 수 있을가요? 차분하게 잘 만들어진거 같아요.
