LadyMarry is a project management app specifically geared to help couples plan their wedding from beginning to end. Different areas of planning are broken up into categories (i.e. venue, guests, photography, beauty, etc.), and tasks are scheduled into a timeline specifically catered to you. It also allows you to keep track of your expenses and research vendors at your chosen destination. Since the app is free-of-charge, it can save you big on working with a full-service planner as you can handle much of the details on your own.
