### 1/5 — Hopeless

*2025-12-02, version 3.0.2*

This app is hopeless. It is the worst part of my job. And that’s saying something.

### 1/5 — Terrible App

*2023-08-01, version 2.0.14*

This app looks and works almost as bad as the internet websites in the 90's. It is shocking these app developmer are charging so much money to orchestras for this prehistoric thing! I'm hoping someone else comes along with a proper system and app that works to today's standards so these people stop getting money for this horrible app. It is a disaster.

### 2/5 — iPhone app login fields misaligned

*2023-07-18, version 2.0.14*

New problem with this app on iPhone 

All the login fields are one online out for data entry… so to enter each, you need to click on the space above (for first field) or field above for each, including the “submit” button. The app had been pretty good up until this… now it is really problematic. Not sure what happened?

### 2/5 — Crashes

*2023-07-18, version 2.0.14*

Trying to use on macbook air -- works on all other apple devices, but on the macbook app it crashes whenever I try any field to log in.... Hope this is fixed soon as it is a great app!

### 1/5 — Unterirdisch!

*2023-04-22, version 2.0.14*

Jedes Mal ist die Neuingabe der Login-Daten ein Geduldsspiel, ach was, ein Glücksspiel!
Gebt doch bitte auf, damit der Arbeitgeber endlich ein funktionierendes System kaufen muss!
Oder werdet kostenpflichtig und stellt ein paar 11-Jährige bekiffte Teenager ein, die besser Coden können.
(Kunigunde/Württembergische Philharmonie)

### 1/5 — Login nicht möglich, daher leidder unbrauchbar.

*2022-03-01, version 2.0.13*

Schade.

### 1/5 — Exceptionally badly designed

*2021-12-06*

The fact that this mobile app (or indeed its desktop version) is actually used by major symphony orchestras is proof of just how small, and uncompetitive the market for such software is. This mobile version provides little more than a pared-down calendar, with no rosters or library functions. Perhaps it works better in German.

### 2/5 — Unglaublich

*2021-10-25, version 2.0.10*

Liebe Entwickler, sagen sie, ist es wirklich so schwierig die ganze Geschichte mit Login Normal zu machen?! Ich muss mich fast jedes Mal neuanmelden, wenn ich dass app starte! Es nervt.

### 1/5 — Ungenügend

*2020-01-15, version 2.0.6*

Das iPhone ist nun für opas nicht mehr zu gebrauchen!

### 1/5 — Update

*2020-01-15, version 2.0.6*

Ätzende App.Nach neuestem Update geht gar nichts mehr-zumindest auf dem iPhone
