When I was looking through today's app for the first time (a photo app that lets you add funny captions), I felt like it needed a few more options. So I contacted the dev (awesome guy) and got him to let me add a few more (even crazier ones!). Sweet! And I couldn't resist adding "YOLO" to the list too...because, well, YOLO.
InstaCaption does exactly what its name says: take or choose a photo from your camera roll and then let the app instantly generate a random caption. If you're not satisfied with the selection, you can keep "re-capping" until you find one you like. Drops from $3.99 to FREE!
