这个世界没有真正的感同身受。 一个事实是,每个人都是一个孤岛。另一个事实是,人和人之间必然存在丝丝羁绊。它的存在,可能因为我们身处同一空间,可能因为我们都看向了同一方向,可能因为我们都听了同一首歌,也可能只是因为,此刻,我们在做同一件事。 时间的公平之处在于,不管身处何方,所有人类都在共享此刻。而此刻,在做同一件事的我们,组成了属于我们自己的时空。时间在穿过我们,我们在穿越时光,在CoTime时空中,找到我们的同行之人。CoTime里的我们,同一时空中的羁绊,不在于地域,不在于阶级,不在于条件,只在于,此刻,我们在做同一件事。 这个世界没有真正的感同身受,但在CoTime的时空中,我们也许可能,可以试着理解一下。 ------------------------------------- 时空状态: 每一天的生活,每一段的生命,都由不同的状态组成。在做同一件事、处于同一状态的我们天然组成了一个时空。 去合适的时空同步自己的状态吧!可能是集合干饭,看看大家都在吃什么;可能是一起自习,手挽着手更好上岸;也可能是单身生活,展示不一样的自由自在。 记录瞬间: 一个个的瞬间连接成状态,组装起人生。在CoTime时空里、状态下,记录分享那些值得的瞬间。 旅行路上的一处柳岸花明,发呆过程中的一瞬福至心灵,将醒未醒时一段庄公晓梦,还有人生途中的喜怒哀乐,都能在这里被记录和看到。 找到Co伴: 当你独自行动的时候,你好奇其他人在做什么么?你想,试试看,找到同伴么?在CoTime里找到Co伴们,一起打破空间,穿越时空。 可以看到Co伴在做什么;可以一键传送到时空中Ta所在的位置,一起做些什么;还可以偷偷留言,聊聊一切。 时间统计: 时间都去哪啦? 在通勤,在搬砖,在睡觉,在刷手机; 也可能在陪陪家人,在聚会嗨皮,在好好生活。 在CoTime,把状态打上标签,统计你想记录的时间,看看时间都去哪啦。 CoTime会员服务说明: CoTime会员服务,享受超多会员权益。 CoTime会员包含以下几种订阅价格 非连续订阅产品: 三个月 / 45元 一年 / 99元 三年 / 118元 连续订阅产品: 连续包月 / 12元 连续包季 / 27元 连续包年 / 59元 CoTime会员服务协议: https://web.cotime.com.cn/cotime_vip_agreement.html CoTime连续订阅服务协议: https://web.cotime.com.cn/cotime_subscribe_agreement.html -联系我们- 邮箱:cotime2024@126.com

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.
