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)

Verdict
