Ehrenamtskarte Bayern is a free mobile app designed by Tür an Tür - Digitalfabrik gGmbH for Android users. The app is intended for individuals who hold a Bayerische Ehrenamtskarte, which is a recognition program for those who engage in voluntary work for the welfare of society. The app allows users to access discounts and benefits from public, non-profit, and private establishments by locating their current position in Bavaria.

The app is compatible with both smartphones and tablets and provides an intuitive interface for users to access the current benefits available for the holders of the Bayerische Ehrenamtskarte. The card, which was introduced in 2011, is a joint project of the Bavarian State government and the participating districts and independent cities in Bavaria. It is primarily a way of appreciating people who volunteer their time for the welfare of society beyond the norm. To be eligible for the card, one must complete a minimum of 5 hours per week or 250 hours per year of voluntary work for a minimum of two years or meet one of the special criteria listed on the website.
