Meditation Timer Meiso vs UnDo

Make quiet time a daily habit. Meiso is a meditation timer without ads or subscriptions. Set a timer, keep a session log, and meditate at your own pace. TIMER Choose a preset such as 3 or 5 minutes, or use count-up mode without a time limit. Switch the ending sound and vibration on or off. SESSION LOG Review your activity graph, weekly meditation time, streaks and total time. Achievement badges help you track milestones. APPLE WATCH Use the timer without keeping your iPhone nearby, then sync your session history to iPhone. WIDGETS AND HEALTH Home screen widgets and Live Activities are supported. With your permission, save meditation time as Mindful Minutes in Apple Health. HEART RATE VARIABILITY (HRV) Record and analyze metrics such as SDNN and RMSSD using beat intervals from a compatible Bluetooth heart rate sensor. Apple Watch uses available heartbeat data. Compatible hardware and permissions are required; available data and metrics depend on recording conditions. An iPhone alone cannot measure HRV in this app. HRV displays are reference information for personal reflection. They do not establish meditation benefits or assess your health, and are not for diagnosis, treatment or medical decisions. Consult a healthcare professional for medical advice. YOUR PREFERENCES Light and dark modes. Japanese, English, Chinese, Korean and Spanish. Free to use, with no ads, subscriptions or account registration. Compatible external hardware is obtained separately.

你是否已经厌倦了各种充满压迫感的 To-Do List 和打卡软件？ 一旦中断就红牌警告，没完成任务就充满负罪感——这不该是管理生活的方式。 UnDo 是一款围绕“克制冲动”设计的轻量级应用。它不是监督你“要做什么”的严厉教练，而是一个帮你暂存冲动、拉开反应距离的“欲望降温箱”。 【核心功能】 欲望捕获与冷冻： 当冲动发生时（想冲动消费、想熬夜、想点高热量外卖），别急着行动，先把它写下来并放入“冰块”中冷冻。拉开距离，是化解冲动的第一步。 诚实的主动结算： 冷却期结束后，系统会轻量提示你回看并结清。结果只有两个：我破功了，或者我忍住了。 零压力的失败处理： 如果没忍住，点击“破功”，该记录会直接从本地数据中静默删除。我们不保留失败历史，不累计失败次数，拒绝给你增加羞耻感。 静谧的收集箱： 如果你成功克制了冲动，它将转化为美丽的琥珀，永久存入收集箱中。这里只记录成功，不记录失败。 【产品特色】 极简输入，支持快捷选项与照片附加。 灵活的自定义冷却时长（从 1 分钟到 24 小时）。 数据完全基于本地持久化存储，你的欲望和隐私只属于你自己。 在 UnDo，放下焦虑，享受没有压力的静谧胜利。 （推荐在iOS26进行使用，体验会更好）
