But here’s the catch, you can call all these places at the exact same rate as you would someone standing right outside your doorstep. We even give your very own cell number, and they can call you back on. No SIM swap is needed. Just download the app and presto. Now that’s innovative.

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.
