Want to say, I Love You, with your iPhone but add animation to the message? Smilebox, which is part of Israel’s Perion Network, has released one-of-a-kind mobile Valentines with moving graphics such as flying cupids, throbbing hearts, and floating sentiments.

The animated designs can be shared directly from the app through email and SMS and all creations in the service can be shared via Instagram, Facebook and Twitter.

“Our Smilebox for iPhone Valentine designs take mobile photos to a new level with an animated experience that provides a rich dimension to standard photo sharing,” said Yuval Hamudot, Smilebox president. “Over the last four months, we’ve seen more than 80 percent growth in both new and active users. We expect this new innovation to continue to drive the growth in user adoption of our service.”

The release of Smilebox mobile designs complements an even wider collection of 2013 Valentine designs available on the desktop service for Mac and PC users. The collection provides a broad selection of Valentine’s Day greetings, collages, slideshows, scrapbooks, and invitations.

Smilebox is part of the Tel Aviv-based Perion Network, a global consumer internet company that develops applications to make the online experience of its users simple, safe and enjoyable. Perion’s three main consumer brands are: IncrediMail, Smilebox and SweetIM.
