Tonio is a smartphone App which allocates links to current radio programs.
Tonio can broadcast information with music or tones and can therefore be called the world's first audio QR code. Tonio automatically forwards users to websites. This makes it easy for terrestrial broadcasters to send background info, images, videos or info on promotions about their program.
Zündel used a simple formula for this product:
Tone + Info = Tonio. Even the logo is the logical result of adding the common symbols for tone (sound) and information.

Zündel invented the brand addition, corporate design and logo.
