The app is based on The Love Dare, a non-fiction marriage-related book written by Alex and Stephen Kendrick. It is a 40-day Christian devotional designed to strengthen marriages. Each daily devotion includes scripture, a statement of principle, the days "dare," (such as "Resolve to say nothing negative to your spouse at all") and a journaling area and check box to chart progress. It is used in the storyline for the 2008 film, Fireproof, which is directed by author Alex Kendrick. For Valentine's Day, Day 1 and Day 2 of The Love Dare were published on the Baptist Press' website, with permission of B & H Publishing Group.
