这是一个为 iOS 打造的待办与日程应用,但它并不打算成为你见过的那种。 我们相信,记录事情不应该是一个负担。你不需要先想好格式,也不必在多个页面之间来回切换。只需要把想法说出来,其余的交给 AI 。 DOO 链接的大模型会理解你的自然语言,将零散的输入转化为清晰的待办事项与日程提醒。你不需要学习新的规则,也无需调整自己的习惯。 在交互设计上,应用采用独特的单页结构。所有记录、查看与回顾,都在同一个界面中完成。没有跳转,没有弹窗,信息通过卡片自然展开与收起,始终保持清晰与克制。 在克制的外观之下,是完整而扎实的功能基础。DOO 支持记录单次和重复事项,支持记录子事项,支持记录农历生日与纪念日,支持开启中国大陆节假日与调休、二十四节气等日历日程,并可以订阅外部 ICS 。 它不会强迫你适应复杂的系统,却能在你需要时,提供足够深的能力。如果你在寻找一个安静、专注、真正融入 iOS 的待办与日程应用,它会是一个与众不同的选择。 我们希望,DOO 能成为你每天愿意打开的那个应用,而不是又一个被下载后遗忘的工具。 DOO 提供自动续订订阅服务「DOO PRO」。订阅后可解锁以下会员服务: - iCloud 同步与自动备份 - AI 智能语音识别与录入 - 桌面小组件解锁 - 自定义 ICS 日历订阅 - 全部功能与后续新特性更新 订阅方案与价格(中国大陆地区): - DOO PRO 月度会员:6元/月(自动续订) - DOO PRO 年度会员:60元/年(自动续订) - 新用户首次订阅优惠价:月度 2元/月,年度 20元/年 说明:优惠资格、适用范围与最终结算价格以 App Store 实际显示为准;不同国家或地区价格可能不同。 自动续订与扣费说明: - 确认购买后,费用将从您的 Apple ID 账户扣除。 - 除非您在当前订阅周期结束前至少 24 小时关闭自动续订,否则订阅将自动续期。 - 系统会在当前订阅周期结束前 24 小时内扣取下一周期费用。 - 您可在 iOS「设置 > Apple ID > 订阅」中管理或取消订阅。 - 取消后,当前订阅周期内的会员权益仍可继续使用,至周期结束时失效。 - 如提供试用权益,购买订阅后未使用完的试用期将失效(如适用)。 - 可在 App 内使用“恢复购买”恢复已购订阅。 - 退款与账务问题以 Apple 官方规则为准。 使用条款(EULA): https://www.timelikesilver.com/apps/doo/terms 隐私政策: https://www.timelikesilver.com/apps/doo/privacy
