the 3M company's Post-It Notes are one of the world's most readily identifiable products, and the PopNotes apps complement Post-It Notes with a utility for creating and maintaining a set of virtual Post-It Notes. the PopNotes app was designed to combine 3M's recognizable branding with Windows 8 and Windows Phone 8's modern, fluid user experiences.

mobi designed the PopNotes Windows 8 app to incorporate Windows 8 design elements with the then existing iOS apps. mobi also designed and developed a more unique version of the PopNotes Windows Phone 8 app to bring the app to Windows Phone 8's users, overcoming obstacles related to memory and performance of Windows Phones restrictions whilst still providing a consistent experience.
