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

Verdict
The clearest difference is ratings volume: ReminderStats at 5 against DOO's 1. ReminderStats also leads on device support (3 vs 1) and iOS requirement (15.6 vs 18.0). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. DOO sells 2 in-app purchases, starting at $0.99 per month and ReminderStats sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for DOO against 5.0 for ReminderStats. That said, the two scores are not equally well evidenced: ReminderStats has 5 ratings behind it against 1, so its average is the more settled of the two.
DOO ships an update fortnightly, ReminderStats every 11 days. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
