About the studio
Creative music apps from Taipei, Taiwan.
BW Innovation is a studio shaped by musicians, designers, and software developers. Our work sits where musical intuition meets practical engineering.
The earlier BW Innovation archive introduced PianoAngel, an iOS app made to help people play piano beautifully and easily. The current app lineup continues that same direction: making chord performance, MIDI harmony, and expressive touch control more approachable.
