A tiny ritual to stay connected with loved ones through patterns in time. Some minutes are too perfect to keep to yourself. 11:11. 12:34. 12:21. 22:22. A few times each day the clock lands on something beautiful — and for one minute, it belongs to you and the people you care about. Sync turns that tiny moment into a reason to reach out. Catch a magic minute, send it to someone you love, and you've said "thinking of you" in two taps — no feeds, no scrolling, no pressure. HOW IT WORKS - Catch the moment — when the clock hits a meaningful minute (a repeat like 11:11, a run like 12:34, a palindrome like 12:21, a mirror like 13:13), the SEND button lights up. - Send it to the people you love — pick your friends. They get a gentle ping and 30 minutes to catch it back. - Stay close — when someone catches it back you both score a little, but the real win is staying in touch with people you actually know. - Look back — your Discoveries log keeps every rare minute you've shared and who shared it back. WHY PEOPLE LOVE IT - A 60-second ritual, not another feed to scroll. - Stay close to the people you already text. Add friends from your contacts, or anyone by name and number with a full country-code picker — no contacts permission required. - Invite the rest. Not on Sync yet? Send a one-tap text invite. - A real reason to glance at the clock. Suddenly 11:11 means someone. Your contacts stay on your device — Sync never uploads anyone you don't add as a friend. Sync is free and made for the people you love. Catch the next magic minute and stay connected.
