Tapdeck was originally a way to have random backgrounds on your phone, but has recently evolved into a much more feature packed app. They have just brought out a new feature called Collections.
Collections is an easy way to discover new relevant content. Think of Collections like how Flipboard handles magazine subscriptions. The categories you pick will decide what wallpapers are shown. For example, “if you follow the Interior Design collection your wallpaper stream will contain nice designer furnitures”.
Currently, there are 30 different Collections ranging from Fashion to Science and all in-between. Each collection contains hundreds of pictures and will be updated on a daily basis.
However, you can also add your own Collection. If you like movies, you could create a collection of your favorite movies and others who like movies can follow you. Since this feature just launched, you have a big opportunity to gain a large following with you collection.
