Pro Party Planner (download for iOS) serves as your event planner.

Once you know how many guests are coming, create a task list to get everything done before the big day. The feature also lets you set reminders, so you won’t fall behind. You’ll need to set a budget and start building your shopping list for the party. Track your budget for food, decorations and party favors.

Manage guests attending by sending them invitations and checking off RSVPs. If applicable, create a seating chart with Pro Party Planner’s augmented reality feature to better visualize what your party will look like.
Pro Party Planner costs $5 to download, plus $1 per month.
