Read full description

Restraint Log is an offline self-management app focused on impulse control, habit rebuilding, and long-term reflection. Instead of being just another check-in app, it provides a complete loop: trigger awareness, replacement actions, and data-driven review. It is designed to help users gradually reduce relapse patterns, build healthier routines, and maintain clear personal boundaries over time. No mandatory account. No backend dependency for core usage. Your data is stored locally by default for privacy-oriented long-term tracking. Key Features Count Tracking & Analytics One-tap daily count logging with undo. Automatic metrics: today’s count, monthly total, monthly daily average. Line chart, bar chart, and pie chart for trend analysis. Monthly calendar view to visualize daily distribution. Daily Check-in Rate your daily condition from 1-5. Track last 14 days and streak consistency. Turn subjective feelings into measurable progress signals. Trigger & Urge Logging Record trigger, intensity, and response action. Build your “context-emotion-action” pattern map. Quickly review recent logs and identify risk windows. Journal & Reflection Log key events and one gratitude point each day. Built-in reflection prompts for low-friction review. Focus on recovery speed and strategy improvement, not perfectionism. Emergency Toolkit & Breathing Session “Breath Regulation” animated mode with expanding/contracting circle guidance. Countdown-based calming session for high-urge moments. Practical emergency steps for immediate de-escalation. Knowledge Library & Micro Habits Curated knowledge cards, micro-habit checklist, and FAQ. Supports behavior change through environment design and replacement routines. Multilingual & Privacy Supports 8 languages. Includes User Terms and Privacy Policy (CN/EN) in one screen. Lightweight, offline-first, privacy-focused. Who It’s For Users working on self-restraint, nofap/reboot-style behavior change, and impulse control. Users who want to break the relapse-shame-dropout cycle. Users who prefer practical, measurable, sustainable self-improvement. Recommended Routine Keep it minimal: one daily check-in + one short journal entry. When urge rises, run a 60-second breathing session first. Review charts weekly and optimize strategy gradually.

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)
