Hexa Puzzle Hero

Bundling ear training, music theory, and sight-singing, NoSheet teaches you the tools you need to improvise and learn every time you listen. Find intervals, melodies & chord progressions by ear and sing the sounds your instrument makes before it makes them to find your musical voice.
NoSheet is set up so that you can press play, pick up your instrument, and only tap the screen again when you've had enough. That means everything you learn is with your instrument - no learning theory to later tediously translate onto your instrument.
