How HeyFiancé works, in more detail than the homepage.

Can my partner see my answers before they've answered?

No. Your answer stays locked until your partner has answered the same question, and that lock is built into where your answers are stored, not just hidden on the screen. There's no setting, trick or shortcut that shows it early, and we test that every time we change anything.

How does it decide whether we agree?

With a few simple rules, the same every time, as soon as you've both answered. There's no scoring behind the curtain:

Priorities are the one exception. You each rank what matters most—food, photos, venue, music, guest experience, attire, decor, honeymoon, keeping costs down—and that never counts as a disagreement. Your two rankings are combined into one, which HeyFiancé uses to suggest moving a little of the budget toward your shared top two. It suggests. It doesn't move anything.

What's the reveal?

When you've both finished a set of questions, you get a screen rather than a notification. Matches animate in one at a time, with a small celebration for each. The things that need a conversation come last, deliberately, and they're framed as a conversation rather than a problem. It's the one part of the app designed to be fun rather than useful, and it's where most people find out they've been worrying about nothing.

What does a decision actually do?

It changes the plan. Decisions add the work they imply, which is the reason this is a planner rather than a quiz. A few examples:

• Outdoor ceremony adds a rain plan, a tent quote, and a weather-backup line in Rentals.
• Destination wedding adds a hotel block, guest travel info and welcome bags, and moves your save-the-dates to eight months out instead of six.
• Bring your own vendors adds catering, rentals and bar service as separate things to book, plus a line for tables, chairs and linens.
• A friend officiating adds a legal check on whether they can actually do that where you're marrying, and sets the officiant budget to zero.
• Writing your own vows adds a task to write your vows, six weeks out, which is later than you think and earlier than you'll want.
• A full open bar makes the bar cost per person, so it moves with the guest list.

Change your mind and it unwinds: tasks it added that nobody has started are taken away, and the new decision adds its own. Anything you've touched, assigned or left a note on stays, because HeyFiancé assumes one of you was mid-thought.

What if we don't have a date yet?

That's where most people start. Tasks are grouped by roughly when they happen (getting started, a year out, nine months, six, four, two, one month, the final week, and after), so the list is useful with nothing booked. Add a date and every task gets a due date, counted back from the wedding. If you've got less time than a task usually needs, it's marked catch-up rather than overdue, because being told you're nine months late on the day you got engaged is not helpful.

What stops it becoming another overwhelming list?

A hard limit. The home screen shows at most five things, in this order: payments due in the next two weeks, then tasks that are overdue or due soon, then tasks you can actually start now, then the questions if you're behind on them, then one card for anything waiting to be talked about. The other seventy tasks exist and you can go and look at them. They are not on your home screen.

Anything can wait until next week. Nothing nags.

How much does it cost?

$39, once, per couple. Both of you are included, and there's no subscription. Most wedding software is free because vendors pay for it, through ads and referral fees. HeyFiancé has no vendor directory and nothing to sell to anyone, so the only person it answers to is the two of you.
