Jour J : Mariage

Planning a wedding isn't a decision; it's months of meetings, deposits, and lists. Jour J keeps track of everything for you, and together.

Give us your date, an estimated number of guests, and the app instantly provides you with your complete wedding plan: dated tasks, an initial budget, and a countdown.

A REAL TOGETHER

Invite your partner with a six-digit code sent via SMS or WhatsApp: no account creation required. You'll see the same budget, the same guest list, and the same plan, updated on both sides, and each of you will be notified when the other makes progress.

SHARE THE TASKS

Thirty dated steps from your wedding day, from the town hall paperwork to the final check from the caterer. Assign a task to one of you with a swipe, add your own, or choose from pre-made lists (religious or secular ceremony, bachelorette party, day after). The hour-by-hour timeline of your big day can be sent to your witnesses with a single tap.

THE BUDGET, YOUR OWN AMOUNTS

Set your own budget item by item; until you do, the app displays the average French budget for your region, season, and number of guests. Deposits, balances, total budget, and cash flow month by month.

THE SEATING PLAN, TO SCALE

Your venue and tables in real life, down to the meter. Move tables with your finger, place the dance floor, buffet, or stage, and drag a guest to their seat. Automatic seating groups together and avoids any dietary restrictions.

GUESTS, WITHOUT RE-TYPING

Import your contacts (only those you select are saved) or paste a list. Groups, RSVPs, dietary restrictions and allergies, then the caterer's list and place cards to print.

GUEST PHOTOS

A QR code on the tables: your guests upload their photos without installing anything, and you can find everything in a private gallery.

OFFLINE

Everything works without a network connection, even in a venue in the middle of nowhere. The backup automatically updates when you reconnect to the network.

WEDDING DAY PRO

The free version lets you plan a complete wedding for up to 40 guests. The Pro subscription unlocks unlimited guests and tables, automatic seating, all milestone notifications, monthly budget tracking, printable documents, and unlimited photo uploads. One subscription covers both of you.

Two plans: monthly (€6.99) with a one-week free trial, or annual (€39.99) with a one-month free trial. Payment is processed through Google Play; the subscription renews automatically and can be canceled at any time in Google Play. When you stop using the app, nothing is deleted.

No ads. No ad trackers. No resale of data.
