The My Project app, created by Jam, enables users to 'Create a New Project' and drag and drop photos into the templates available, and add tips.
They can then share these tips on Facebook and Twitter.
Keval Shah, Wickes digital marketing manager, said: "The app helps to express the real sense of pride homeowners and tradesmen get when successfully completing a project."
The app is being supported by Facebook advertising, direct email and a blogging campaign.
TV and direct has largely been the mainstay of Wickes' marketing mix, but the retailer has been expanding its digital marketing.
This is the first work Jam has done for Wickes after it was appointed as its social media agency in March.
