Despite living in an age of digital everything, the most effective way to brainstorm often involves the humble pen and paper. Creativity can flow easily from the free form act of scribbles on Post-it notes around the boardroom table. The trick is whipping these notes into shape. Unlike the strictly digital Stickies app for the Mac or similar, 3M (maker of the original Post-it) has come up with an iOS app that snaps your paper notes, recognising up to 50 at a time, and places them on a virtual board.

From there you can export in plenty of formats (image, PDF, PowerPoint slide), save to Dropbox et al, or simply share by email or social media. When used with Evernote writing on the notes is recognised as text and becomes searchable. postit.com/app
