Pfandgeben is a social and communication app developed by Christoph Reinders that allows users to donate or collect pledges. With this app, you can easily get rid of your empties or find pledges in your area. The app also offers a chat function that enables donors and collectors to communicate and coordinate details about the donation.

If you want to donate your pledge, you can create an offer in the app by specifying your desired pickup location, the quantity, and the time. The app will automatically find a collector for you. Alternatively, you can contact pawn picking in your area directly by phone to deliver your pledge.

If you are looking for a pledge, you can find offers in your area on a city map. You can also receive push notifications on your smartphone when new offers are available. Once you accept an offer, you can communicate with the donor via the chat function to discuss details of the donation.
