Plenty of apps take retro or vintage imagery on your mobile phone, the pick of which are featured here. But here's something to add retro effects to your existing photos - Pixlr-o-matic.
Fancy creating your own Andy Warhol artwork on the go? You can with the newly-launched The Warhol: D.I.Y. POP app for iPhone and iPad.
The work of the Andy Warhol Museum, it's a way of turning your own photos into Warhol-style imagery - or 'digital silkscreen print' as they call it. Take a photo with your camera or use one from your library, then use crop, expose and underpaint to create your image. It might take time, but you'll get there eventually.
Also throwing in some words from artists and curators at The Warhol, plus 'inside information' on Warhol and his art, the app is available to download now, priced at £1.49.
