KeyFly Piano app analytics for September 5

Two birds fly across a staff. Quill takes the treble line and your right hand; Thump takes the bass and your left. Tap when a note reaches them. Songs are ordered by what they ask of a child, not by title. Song one is five keys under five fingers. By song 126 both hands are playing a full arrangement. Nothing is skipped and nothing is padded. Every song can run at 0.6×, 0.8× or full speed, one hand at a time, with a metronome click and a tap in the hand on every note. There is no timer and no penalty for stopping. Free to play. A Pro pack opens every song at once and lets you import your own music.
