Nik Software's popular image editing app Snapseed will be available for free on iOS and half price on the Mac for one day only this Valentine's Day.

Snapseed for iOS, which has been available since last November, is available for free and the Mac app, which was only released at the end of last month, will cost £6.99.

The Mac app brings the same easy-to-use features to the desktop, letting you enhance, transform and share your photos directly from your Mac.
