"Because there isn't an app for everything."
When we're wrapped up in our devices, it can be hard to see the obvious: life's most exciting moments aren't usually found online.
To remind us of this, a group of students from Sweden designed a sticker that says "Not available on the App Store," adapted from the ubiquitous Apple App Store badge. The students have started plastering the stickers on perks of the physical world - namely, everything in an old school playground. The stickers are available for purchase here or you can make your own.
