The Pinterest mobile app has an interface that is aesthetically pleasing and straightforward, opening with only 4 buttons superimposed on a full-screen home feed. This appeals to the target audience for Pinterest, which is all ages 12+, but a heavy portion are older adults. The home feed learns what the user want to see based on activity and is effective at doing so in my experience. If you like a post, with a few clicks you can create a new "Board" (which is just a photo album with links). Pinterest's most innovative and effective feature is its "Pin it" feature button which allows you to create a Pinterest post of an image on any website and save it to a board. This can be done on the mobile app using the "Share..." feature and clicking "Pin it," without leaving that page. My mom, an interior designer, uses this app for client meetings and when on-site without access to her computer. She and her clients add to a shared private board to create the desired look. The app is effective and efficient on the user side making it easy, enjoyable, and practical, which in turn supports Pinterest's objective of capturing users' attention and increasing activity.
