This app, paired with the Mac app (and I think soon the iPad app), is by far the best sermon prep software I’ve ever used, and I’ve been in the market since 2007. Most of the others seem to focus on the database side of things - cataloguing your sermons. While Sermon Design does this, it really shines in helping you craft and develop your sermon. I especially love the Structure part, where you can choose from a wide variety of sermon styles to organize your contents and main points. Even though I’ve only been using it for a short time, this is one of the most productive apps I have as a pastor, because it does help make my sermons better, simply by letting me “see” what I’m thinking as I put the ideas into words and images. I would call this a “must-have” for people in ministry.
