Not very good – HSK Vocab List - Fast Memory - Level 1 to Level 6 Review

This app shows the HSK vocabulary lists, but is missing several key features required to make it really useful. It does not show PinYin or provide sounds of the pronunciation, you are on your own to quiz yourself or keep track of which words you remember. Not worth it considering other free alternatives.
