Music Tools and Widgets is an iOS app for musicians designed, developed, and launched by Kilian Günthner. The app rethinks everyday music utilities such as a tuner, metronome, pitch reference, and keyboard by moving them beyond the traditional app interface and into Apple’s system-level surfaces, including widgets, the Lock Screen, Control Center, Live Activities, and the Dynamic Island. Built for rehearsals, lessons, choirs, orchestras, and individual practice, Music Tools reduces the friction between musical intent and technical action. The project has been covered by TapSmart, Sheconomy, Illumulus, Kölner Stadt-Anzeiger, and Kölnische Rundschau, and has been recognized for its thoughtful product design, technical execution, and musician-centered interface architecture.
