Four things you're holding at once
The maid of honour usually ends up running the bridal shower, which means juggling a guest list that spans the bride's family, her work friends, and you; a gift list you have to mention without making anyone uncomfortable; an afternoon that shouldn't fall flat; and a final headcount for the cake and the tea. A single page built for the day keeps all four in one place, where you can reach them from your phone.
There isn't a bridal-shower design waiting in the app yet, so you begin from the nearest shower setup and write your own plan onto it. What carries over is exactly what a shower needs โ a shareable invitation, replies tracked against names, plus-ones inside your limits, and room to phrase the gift list kindly.
