Memory Stamps is a free Android app developed by David Strnad that helps collectors and travelers keep track of their collections of tourist stamps and stickers. With a simple and intuitive interface, the app allows users to add stamps to their collection, search for specific stamps by name or number, and sort stamps by various criteria such as category, region, and distance. Users can also rate each stamp on a scale of one to three stars and synchronize their collections with the official website of the Czech Tourist Stamps using the app's official API.

Other features of the app include the ability to share collections and individual stamps on social media, view detailed information about each stamp, such as its location, images, and selling points, and access GPS coordinates of each stamp. The app also offers an automatic database update feature and is available in Czech, Slovak, and English. While the app is not currently compatible with the new Czech Tourist Stamps website, users can still enjoy its many features and benefits.
