I am hoping that by the time you wed you will know this answer, but if not, you might gain a little insight--or have a little fun-- with the new Do You Know Your Groom App. It is launching from Sourcebooks today, July 15, starting at 99 cents.

Since brides spend a lot of time on their phones, planning their weddings, the maker of this app figures this will be yet another bridal accessory. They consider it the most entertaining way to discover all about your husband-to-be.

Honestly, I can think of other ways to discover more about your man, but, might as well enjoy a little fun amidst the craziness of wedding planning.

And, there are His and Her apps. The Do You Know Your Bride App is also available to test the groom’s knowledge.

Says the press release: "Based on the bestselling wedding books by the same name, these apps can be a great way to spend a night (or two) learning more about each other. Even after years of dating, there are sure to be surprises."

"The Do You Know apps are totally unique quizzes that brides and grooms can’t find anywhere else. Couples should expect to laugh a lot and playfully argue as they try out probing questions.
