Konzertmeister is an Android app developed by Stefan Stift that aims to simplify the appointment management of orchestras and choirs. As the success of every musical performance depends on good rehearsal work, Konzertmeister provides a clear and structured schedule for rehearsals and performances, making it easier for everyone involved to maintain an overview.

The app eliminates the need for various communication channels such as SMS, email, WhatsApp, or Facebook, which can often make it difficult for members to keep track of appointments. With Konzertmeister, members are presented with a clear and concise schedule, with the option to accept or reject appointments with just one click. This feature allows the musical director to easily observe the attendance status of members, ensuring that the planning is adjusted accordingly.

Konzertmeister also provides a detailed structuring option, allowing members to be divided into sections, making it easier to define part or register rehearsals. Additionally, the app offers the option to import appointments into a private calendar, making them available outside the app at any time.
