At SXSW, Samsung unveiled a new groundbreaking app that automatically converts your humming into sheet music. Hum On! comes with instant playback, so that the musically inclined can jot down a melody on the go, without needing a pen and paper. The C-lab developed app also allows users to arrange the melody to several genre presets like R&B or rock.

Unfortunately, the app is still in the beta stage, which means you have time to learn how to sing on key.
