Back in the olden days, like thousands and thousands of years ago, you’d propose enough times that someone said yes. And then you were off to the races, if the races were myriad wedding-planning problems.

Back in the not very olden days, like an hour ago, you’d be considered fancy if you had an actual wedding planner. A person. Films have been made about this.

But today, you need your smartphone and a whole category of apps made just for you:

Wedding apps have become increasingly popular in the last few years as millennials begin to wed. “We got Facebook in college, we got the first iPhones,” 27-year-old Ajay Kamat, who co-founded the photo-timeline app Wedding Party, told TIME. “We have an expectation that when we travel or shop or do anything, there are services and apps that will help make that experience better for us.”

These smart apps—which are trying to break in to the $53.3 billion wedding industry—help brides and grooms send invites, organize guests, hire local vendors, gather all the photos guests take, register for gifts and crowdsource money for honeymoon activities. Apps like Appy Couple, Carats & Cake and Wanderable are becoming favorites among savvy couples who want to streamline the logistics associated with events like bridal showers, bachelor and bachelorette parties, the rehearsal dinner, wedding and honeymoon.

Bet the iPhone apps are better than the Android ones.
