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

Snapseed for iOS, which has been available since last November, will cost £1.49 and the Mac app, which was only released at the end of last month, will cost £6.99.

Snapseed for iOS was considered to be good enough to earn a Macworld Editor's Choice award, particularly impressing with its simple interface and Control Point technology.

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.
