The Postcard app enables users to send e.g. holiday snapshots as real postcards. Users can edit their photos, easily enter text and select addresses directly in the app. Furthermore, the unified interface allows intuitive use and makes it fun to use the app. Postcard saves long searches for postcards and stamps in the holiday country and connects the digital to the analog world: With Postcard, users can share personal emotional moments from the digital world in an analog way, e.g., with their grandparents or friends who do not own a smart phone.
