Das Rathaus ist das bedeutendste weltliche Bauwerk der Stadt Aachen. Generationen seit Karl dem Großen haben es geprägt und ihre Spuren hinterlassen. Der Kulturbetrieb der Stadt Aachen bietet mit dieser App die Möglichkeit, mit moderner Technik in die mehr als 1200 Jahre alte Geschichte des Aachener Rathauses einzusteigen und das Rathaus in seinem heutigen Zustand kennen zu lernen.
Besonders erwähnenswert: 
- Möglichkeit eines Rundganges durch alle Räume mit Hilfe von 360°-Aufnahmen. Dabei können auch Räume besichtigt werden, die der Öffentlichkeit sonst nicht zugänglich sind (Zimmer des Oberbürgermeisters oder der beeindruckende Dachstuhl).
 - Das Glockenspiel, das sonst nur in bestimmten Intervallen ertönt, kann angehört werden.

KHM App's advantage is update cadence (fortnightly vs every 20 months). On price, ads, monetization model and device support there is nothing between them.
