We've seen plenty of novel screen protector application systems, but Tylt's new ALIN ($25) might be one of the smartest yet. Coming with three clear films, an anti-glare film, a cleaning cloth, and a squeegee, the key to the system is the plastic alignment tool. Your iPhone 5 or 5s snaps into it, providing a guide for the installation of the film. Just line the edge of the film up with the edge of the plastic, lay it down, and squeeze out any bubbles.
