Seven questions a day. From a shared daily set. You answer first. Then you do the harder part: guess what percentage of everyone else answered the way you did. At 21:00 the curtain lifts and you find out how well you actually know people. Most of the time you are wrong. That is the whole point. HOW A DAY WORKS 1. Seven questions land at midnight. Ordinary things — how you hang the toilet roll, whether you rinse pasta, what you would do with a wallet you found. 2. Tap your answer, then predict the split. Change your choice until you tap “Lock it in”. 3. After locking, answers cannot be changed and nobody sees anyone else's first. 4. From 21:00, see your daily result summary free, once the reveal is published. WEDNESDAY IS CIVIL WAR DAY One question a week is chosen because it splits people close to fifty-fifty and neither side can believe the other exists. The screen divides down the middle and choosing an option means joining a side. You get a team name. WHAT YOU FIND OUT ABOUT YOURSELF Free shows whether you are with the majority, in the minority or evenly split, how close your guess was (Close, Near or Off), your streak and daily grid. With fewer than 20 answers, everyone sees counts instead of percentages, with no score. SYNC Premium adds exact percentages with 20+ answers, your region vs the world when comparable data exists, calibration and rarity detail, Editors vs you where an editorial guess is available, week and month numbers when there is enough history, and every day you have played in the archive. Your first viewed reveal includes that day's question and summary detail free. DUO After your first viewed reveal, a card on Today offers to invite someone. Pair with one person and guess each other. Duo joins the bottom bar once you have a pair. THE QUIETER QUESTIONS Some days go deeper — what you would forgive, what you have never admitted, what you would do differently. Those answers are never shown next to your name, on any card, to anyone. The question is hidden on shares too. The rule is in the security rules, not in a promise. WHY A DAILY SET Because a comparison only means something between answers to the same question on the same day. There is no feed, no infinite scroll, nothing to catch up on. Seven questions, one reveal, done. Available in 24 languages. SUBSCRIPTION Eligible new subscribers can try the yearly plan free for 7 days where offered. Eligibility and the offer are confirmed by the store. SYNC Premium is an auto-renewing subscription, monthly or yearly. Payment is charged to your Apple ID at confirmation, or after an applicable free trial ends. It renews automatically unless turned off at least 24 hours before the period ends, and you can manage or cancel it in your account settings at any time.

About

小日子 Our Days

Features
Read full description

Our Days is an app made for two. The days you've been together, the dates that matter, notes to each other, and little games to play — all in one place. No accounts to sign up for: one of you creates a pairing code, the other enters it or scans the QR code, and your phones are connected. Works on iPhone, iPad, and Apple Watch. [DAYS TOGETHER] Set the day you got together and the home screen keeps counting. Birthdays, anniversaries, Christmas, Valentine's Day — see what's coming at a glance. Long-distance? Set the date of your next meet-up too. [BOARD] Share one chalkboard: write by hand, type, and erase when you make a mistake. The board shows up right on your partner's Home Screen widget and Apple Watch. With Pro you can add up to three photos, move, resize, and rotate anything on the board, and use colored chalk and a second handwriting font. [HEARTS AND HUGS] Missing them? Tap the heart and your partner gets it right away. Both hold the heart at the same time, and that's a hug. [THIS OR THAT — GET TO KNOW EACH OTHER] A few questions a day like "Early bird or night owl?" Answers are revealed only when you've both picked, so you can see how in sync you are. React with emoji and quick replies, or type up to 3 messages per question; with Pro, send voice notes and photos and chat without limits. [PLAY TOGETHER] Telepathy, Tic-Tac-Toe, Draw & Guess, Big Two, Slapjack, Old Maid, Ludo, Yacht Dice, and more. Get "All Games for 7 Days," Pro, or "All Games Forever" to play everything — only one of you needs to buy, and both phones unlock together. Locked games can be tried free once a week. Shake your phone to roll the dice in Ludo and Yacht Dice. When you're in the same room, connect directly over Bluetooth or Wi‑Fi. Games are just for fun: the loser can agree to do a little something, like drying the other's hair. [LIVING TOGETHER OR LONG-DISTANCE] Living-together mode adds a shared shopping list; long-distance mode shows both of your local times and a countdown to your next meet-up. [LEVEL UP] The more This or That questions you answer together, the higher your level — from "Just Connected" all the way to "Legendary Couple," 11 levels in all. When you level up, you each hold to stamp it and get a postcard for "Our Journey," and you can turn it into a Story styled as a boarding pass, movie ticket, train ticket, or receipt. There are 5,000 questions, and old ones come back as look-back questions once you've answered them all. Levels have nothing to do with purchases. No ads, no tracking. Your data syncs only between the two of you. [PLANS] • All Games for 7 Days: 7 days at a time, does not auto-renew, can be stacked • Pro Monthly, Pro Yearly: all games + voice, photos, and unlimited chat in This or That + photos and move/resize/rotate on the board + colored chalk + the extra handwriting font. Auto-renews; cancel anytime in Settings • All Games Forever: one-time purchase that unlocks every game forever (Pro features not included) All plans are shared by the paired couple.
