Learn the words to the songs you love.

Sixty-six songs, from Teresa Teng to Jay Chou, ordered by how much of the vocabulary you already know. Pick a song and the app shows you every word in it that is new to you, lets you add them to your plan, and gives you a line-by-line lyric sheet with pinyin and a gloss for each line. Follow along in karaoke mode with your own timings, or memorise the song a line at a time.

The app never ships song lyrics. You bring your own from wherever you have them, and the app keeps them in your own iCloud, private to you. A few songs whose words are classical poems in the public domain come with the text built in; 但愿人长久, Faye Wong's setting of a Su Shi poem, is one of them and is the song in the screenshots.
