Count down to the big day with the people who are waiting for it too. A trip, a birthday, a wedding, the day you finally see each other again: create one countdown, share it, and nudge each other every day until it arrives. SHARED COUNTDOWNS Create a countdown and choose the mates you want to invite, or keep it personal. Invite someone new with a link, a 6-digit code or a QR code. Everyone counts down to the same day, and updates sync to every member. NUDGES, REPLIES AND STREAKS Tap the bell on a countdown card to send a nudge, a little "I'm thinking about it too". Add an emoji or a short message and keep talking in the replies. Type @ to tag a friend in a nudge or a reply, and they get a notification. Web links in nudges and replies open with a tap. Nudge each other every day and your streak keeps growing. PHOTOS AND SURPRISES Give each countdown a cover photo, drop emoji pings onto pictures, and hide surprise photos and messages on the reveal wall. They stay locked until the day arrives. WIDGETS AND LIVE ACTIVITIES Home Screen and Lock Screen widgets, all free. A Live Activity shows the final stretch on the Lock Screen and in the Dynamic Island. Send a nudge right from the widget. WHEN THE DAY ARRIVES Confetti on the day, the surprises unlock, and the Countdown Wrap sums up the wait: how many days you waited, who showed up and with how many nudges, the busiest day, the loudest reaction and photos from the countdown, in one card you can share. Your yearly recap shows your busiest month and your best streak. REMINDERS THAT FIT Get a reminder on the day, a few days before or every day. Add a place and Nudge can remind you when you arrive nearby. Repeat a countdown every year, month or week, pick an event from your calendar, or add a countdown to it. A SECRET SPACE Not every countdown belongs on your main list. Pull down at the top of Home and hold to open your secret space. A secret countdown can still be shared with the people it is for. You can lock the space with Face ID, Touch ID or your passcode; the lock is off until you turn it on. Inside, you can make a countdown where nudges, replies and reactions disappear an hour after they are sent, on every device running Nudge 1.1 or later. FREE, NO ADS, NOTHING TO SIGN UP FOR No ads, no trackers and no in-app purchases. There is no account to create: Nudge syncs through your iCloud account. In 15 languages.

You don't have to open it to see how many days are left. Datto is a quiet countdown that puts the days until your important dates right on your Home Screen. There is no habit to keep. Put it there once, and every glance tells you how long is left. An exam, a deadline, a birthday, a trip, a move — you add the day only once. ■ What it does (free) ・Counts down the days to the dates you care about (up to three) ・Shows one of them in a Home Screen widget (small) ・12 curated colors, plus any custom color you like ・Text color adjusts automatically to stay readable ・A dark appearance — match your device, or keep it light or dark ■ Datto Pro (a one-time purchase, not a subscription) ・As many widgets as you like — Medium, Large and the Lock Screen too ・Unlimited events ・Repeating events (yearly or monthly, rolling over on their own) ・Milestone reminders (100 days, the day before, the day itself — always silent) ・Hours and minutes as the day gets close ・Categories to keep work, family and trips apart ・iCloud sync — the same days on every device signed in to the same Apple Account ■ Made for you if ・You want to keep a goal in view ・You would rather be watched over quietly than nagged ・You like a Home Screen that looks like yours No account, no ads. What you enter stays on your device. With iCloud sync on, it lives only in your own iCloud. To improve the app, only anonymous usage (such as which screens were opened) is sent. Never your event names, and never your name, email, or advertising ID. You can turn it off in Settings. Simply, the days until yours.
