CoupleSync: Couple App & Quiz

CoupleSync is a couple app built on daily questions for couples: you both answer the same prompt separately, and neither answer unlocks until both are in. It's for couples whose conversations have started to loop, and for long distance couples who need a small daily connection point.

Two kinds of compatibility grow alongside this daily couples game: how alike you are, and how well you actually know each other.

■ Five questions every day
340 questions across nine categories, with a fresh set opening at midnight. Answering the one required question keeps your record and streak going, and the other four are there when you want more. Questions come as multiple choice, scales or open answers, from light preference prompts to things you have been meaning to ask but never quite did.

■ Nobody peeks
You cannot see their answer before writing yours. Send yours first and a waiting screen appears; once your partner finishes, the results open automatically. The moment both are in and the handwriting is revealed is the heart of this shared diary. Because you each answer honestly first and open afterwards, the results are far more interesting than a couple quiz you can game.

■ Compatibility on two axes
Most couple quiz apps only measure overlap. CoupleSync measures two separate things.
• Similarity: how much your tastes and opinions coincide
• Understanding: a couples game of prediction where you guess your partner's answer
The result screen shows how many answers matched and your couple type, and the stats tab splits both axes by category. The longer a relationship runs, the more the second one matters.

■ A map you widen together
As answers accumulate, places that belong to just the two of you light up one by one, like an alley or a lighthouse. The map has nine areas, one per category, each with four landmarks. Each day's question becomes another tile, so within a week you can see what you have been building.

■ Discovery cards and your week
Every day you finish together leaves discovery cards for what you share, what you just learned and your own lines, and you can keep favorites. Fill five days in a week and that week's envelope opens with its discoveries, memories and one thing to talk about next.

■ Why shared journals usually fade
Most paper exchange diaries stall within two weeks. CoupleSync picks the prompts for you each day, and with reminders on it tells you when today's questions are ready. A hundred-question compatibility test is fun that day and forgotten the next; questions for couples mean more when they build up a little at a time. The daily conversation, not the score, is what this couple app is really after.

■ Records that build up
The stats tab shows your last 7 days of scores, your answer times and the days left to your next milestone. You also collect 25 badges and climb seven couple levels as your days together add up.

■ Who it is for
• Couples whose conversations have started to loop
• Long distance couples who need a small daily connection point
• Anyone who wanted to keep a shared journal but could not figure out what to write
• Couples curious how well they actually know each other
• Couples who want a private space instead of a noisy social feed

■ Getting started
Pick a nickname, then share your six-character invite code or enter your partner's. Sign-up is kept to a minimum, and you can look around before your partner joins. Reminders, sound and haptics each have a switch, and the app is available in Korean and English.

With the Duo Pass, one subscription opens the full saved collection and the deeper weekly report for both of you.

Invite your partner and open today's first question.
