Like the Evo, the Shot 3 Retro features an LCD screen — albeit a much smaller one — that lets you decide whether to print a shot. It also supports Bluetooth, and you can use the Kodak Photo Printer app to upload photos to social media or print decent, relatively crisp images from your phone. Unlike the Evo, however, the Shot 3 Retro retails for around $170 and includes a pack of film. It also uses cheaper film; you can often pick up a 60-sheet cartridge for under $20. The cheaper arguably encourages creative experimentation, even if the large 3 x 3-inch square prints feel lower in quality and more flimsy than those from both Fujifilm and Polaroid.
