### 5/5 — Outstanding value for a sophisticated pipe organ app

*2026-06-08*

The NAPO-based music apps have always provided us great value and music reproduction fidelity at the same time. Compatibility with MacOS, iPadOS, and iPhone from a single subscription provides us flexibility that we get from very few other music apps.

### 5/5 — Très fonctionnel

*2026-03-15*

Excellente application, parfaitement fonctionnelle et suffisante pour travailler à l’orgue avec une console midi et un simple iPhone/iPad. Très impressionnant !

### 5/5 — Einfach genial!

*2024-11-16*

Einen riesen Dank an Markus Sigg für diese tolle App <3

### 1/5 — Download geht nicht

*2024-06-16*

…

**Developer response:** Das tut mir leid. Dennoch, bitte machen Sie die App nicht dafür verantwortlich, wenn ein Web-Server, für den wir nicht zuständig sind, vorübergehende Schwierigkeiten hat. In Version 0.7 wird Clavitudo weitere Sample-Sets unterstützen. Dann ist es nicht mehr so schlimm, wenn eines davon mal nicht verfügbar ist.
