Even the most experienced party planners can agree that organizing an event can get... stressful, to say the least. Playing phone tag with different vendors, fielding questions from guests, coordinating catering orders and selecting the perfect signature cocktail; there are a lot of moving parts. The good news is, there are so many ways to stay organized.

These apps, all available for Apple and Android users, can arrange all of your party-planning problems into one folder on your phone. Technology won’t play phone-tag with you, invite a plus one without asking or give a cheeseburger to your vegetarian friend. These apps are specifically made so that even your smallest worries are accounted for. Download these before you start taping Pinterest pictures on a wall and connecting them with thumb tacks and red yarn, going a little insane from lack of sleep and your last conversation with the caterer. Listed from the beginning of planning to the very end, scroll through to make your life easier.
