He has hosted The Bachelor for a number of years, so Chris Harrison should know a thing or two about relationships.

That's why he and Bachelor creator Mike Fleiss developed a new dating app called "At First Sight" - where you can scroll through videos of single men and women and choose who you want to message.

At First Sight is available for Apple iPhone, iPad, iPod touch and Android. For more information, visit AtFirstSight.com.
