App is a detailed and highly informative catalogue, ideal for any collector who specializes in any aspect of German stamps.

Stamp collecting is a hobby. Collecting is not the same as philately, which is defined as the study of stamps. The creation of a valuable or comprehensive collection, however, may require some philatelic knowledge.

German Postage Stamp Catalogue contains the main information about each stamp including:

- type
- d
- colour
- main information
- image

It doesn’t take long in the philatelic community to realize that Germans are among the most ardent stamp collectors in the world. Modern postal systems have their roots in the Metzger and Thurn und Taxis couriers established during the Holy Roman Empire. Prior to the country’s unification in 1871, the states that would make up Germany also issued their own stamps alongside these private systems.
