「墙上的咖啡」来自一个古老而温柔的传统:在意大利那不勒斯,人们买咖啡时会多买一杯「挂」在墙上,留给需要温暖的陌生人。 我们把这面墙搬进了手机里—— 【贴一杯咖啡】 选一个杯子,写下此刻的心情,或想对某个陌生人说的话,贴上咖啡墙。你的心事会安静地挂在那里,等一个有缘人。 【取一杯咖啡】 从墙上取走一杯陌生人留下的咖啡,读读那句写给「不知道是谁的你」的话。也许恰好,就是你此刻需要的那句。 【慢递回信】 想回应这份温暖?写一封不超过 140 字的回信。它不会立刻送达——而是像真正的信件一样,在路上走 12 个小时。在即时消息的时代,我们想保留一点等待的浪漫:信在路上的时间,是期待,也是治愈。 【把温暖传下去】 收到的温暖不必止步于你。你可以向对方道一声感谢,也可以把这杯咖啡继续传递给下一个人,看着一份心意在陌生人之间流转。 【装扮你的咖啡】 用不同的杯型、心情贴纸和场景,让每一杯咖啡都有自己的样子。 【安静、安全的小社区】 · 无需强制注册,可以先逛逛再决定是否加入 · 手机号即可登录,简单不打扰 · 内容经过审核,支持一键举报与屏蔽,让温暖的地方保持温暖 【会员订阅(可选)】 「温暖同行人」为自动续费订阅,提供月度(¥8/月)、季度(¥18/3个月)、年度(¥68/年)三档,具体价格以 App 内购买页与 App Store 显示为准。开通后可解锁全部杯型皮肤、心情贴纸与专属场景(免费用户亦有基础装扮可用),装饰性权益仅自己可见。订阅通过您的 Apple ID 账户扣款,将在到期前 24 小时内自动续费并扣款,可随时在系统「设置 - Apple ID - 订阅」中取消;取消后权益持续至当期结束。 隐私政策:https://wap.dosuncoffee.com/wallcoffee/privacy.html 用户协议:https://wap.dosuncoffee.com/wallcoffee/terms.html 慢一点,没关系。墙边见,取走属于你的那杯温暖。

Verdict
The clearest difference is ads: 墙上的咖啡 at none against Seagull IM's shown. 墙上的咖啡 also leads on update cadence (every 3 days vs every 3 weeks) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
