App Syncs Phone and Tablet Screens to Create One Big PictureThe Mosaic app allows users to sync multiple iPhones or iPads to create one giant screen on which to share files or view photos and video.

Talk about bringing people together. Thefree Mosaic appallows users to sync multiple iPhones or iPads to create one giant screen on which to share files or view photos andvideo——所有with just a swipe to connect the devices.

It started with three college students who wanted a simple way to physically connect their mobile devices. One had been working on a file-transfer interface called Swÿp, and the three decided to combine its technology with what's known as "screen-stitching." The founders, all of whom have been programming and developing for Apple's iOS from an early age, created Mosaic during PennApps, the world's largest college hackathon, and launched it in April.
