每日任务 - 一款有效的极简主义生产力应用程序
构建了一款Flutter应用，限制用户每天只完成3个任务。没有冗余功能，没有订阅，专注于真正重要的事情。这款应用源于Reddit上关于简约生活的讨论。
<p>问题</p>
大多数生产力应用都遭遇了功能膨胀。它们起初简单，但逐渐增加日历、团队、人工智能助手、通知、分析，最终变成了它们曾承诺要解决的复杂性。当我在一个20项待办事项的日常清单中感到窒息时，我发现了Reddit上r/simpleliving讨论的“三个任务规则”。
<p>解决方案</p>
“每天3个任务”正如其名。每天，您选择3个最重要的任务。就这样。
<p>核心功能：</p>
1. 每天计划3个任务（早晨/下午/晚上）
2. 可选的日历同步和设备提醒
3. 任务完成时的微妙庆祝
4. 日历视图的未来规划
5. 深色/浅色主题
6. 以隐私为先（无账户，使用本地存储）
<p>故意缺失：</p>
1. 团队/协作
2. 复杂的项目管理
3. 时间追踪
4. 详细分析
5. 订阅盈利模式
<p>技术实现</p>
技术栈：
1. Flutter（iOS/Android）
2. 使用SharedPreferences进行本地存储
3. 通过device_calendar插件进行设备日历集成
4. 通过flutter_local_notifications实现本地通知
<p>关键决策：</p>
1. 无后端/服务器 – 一切本地处理
2. 无用户账户 – 设计上注重隐私
3. 单平台聚焦 – 移动优先体验
4. 日历集成为可选 – 不是每个人都需要
<p>心理学</p>
研究支持“三个规则”：
1. 认知负荷理论：工作记忆最佳处理2-4个项目
2. 完成心理学：完成任务会释放多巴胺，建立动力
3. 决策疲劳：选择越少，决策越好
当您完成3个有意义的任务时，与半完成15个随机任务相比，心理上的差异是深远的。
<p>开发历程</p>
在看到那条Reddit讨论后，我开始了个人生产力实验。朋友们注意到我似乎压力更小，专注力更强。因为以下原因，我选择用Flutter构建MVP：
1. 跨平台，单一代码库
2. 原生性能，流畅的用户体验
3. 丰富的设备集成生态系统
在原始的Reddit社区进行Beta测试，大家不断表示“不要添加更多功能，保持简单。”这些反馈塑造了整个产品理念。
<p>商业模式</p>
1. 免费增值：核心功能永久免费
2. 高级版：高级日历功能、主题
3. 无订阅陷阱 – 一次性购买理念
4. 以隐私为先的盈利模式（不出售数据）
<p>接下来</p>
目前已在iOS App Store上线，Android版本即将推出。正在考虑：
1. Apple Watch伴侣（因为查看3个任务很有意义）
2. 简单的主屏幕小部件
3. 数据可移植性的导出功能
不考虑的：
1. 网页版本（移动场景是关键）
2. 团队功能（个人专注是重点）
3. 人工智能集成（人类意图 > 算法建议）
<p>重要指标</p>
与DAU/MAU不同，我追踪：
1. 每日完成率（3/3任务）
2. 用户留存率，无需增长黑客
3. 关于减压的定性反馈
早期用户报告称，他们完成了更多有意义的工作，同时感到不那么压倒。这才是真正的成功指标。
<p>试试吧</p>
可在3tasksperday.com和iOS App Store获取。该应用故意保持简单——如果您在寻找复杂的项目管理，这不是您要的。如果您想专注于每天真正重要的事情，这可能正是您所需要的。
由一位厌倦了生产力表演并希望找到有效工具的开发者打造。

Built a Flutter app that limits you to 3 daily tasks. No feature bloat, no subscriptions, just focus on what matters. Born from a Reddit discussion about simple living.<p>The Problem<p>Most productivity apps suffer from feature creep. They start simple but gradually add calendars, teams, AI assistants, notifications, analytics, and eventually become the very complexity they promised to solve. I was drowning in a 20-item daily to-do list when I found a Reddit thread in r/simpleliving discussing the "three tasks rule."<p>The Solution<p>3 Tasks Per Day does exactly what the name suggests. Each day, you choose three tasks that matter most. That's it.<p>Core features:<p>1. Plan 3 tasks per day (morning/afternoon/evening)
2. Optional calendar sync with device reminders
3. Task completion with subtle celebration
4. Future planning with calendar view
5. Dark/light themes
6. Privacy-first (no accounts, local storage)<p>Intentionally missing:<p>1. Teams/collaboration
2. Complex project management
3. Time tracking
4. Detailed analytics
5. Subscription monetization<p>Technical Implementation<p>Stack:<p>1. Flutter (iOS/Android)
1. Local storage with SharedPreferences
3. Device calendar integration via device_calendar plugin
4. Local notifications via flutter_local_notifications<p>Key decisions:<p>1. No backend/server – everything local
1. No user accounts – privacy by design
3. Single-platform focus – mobile-first experience
4. Calendar integration optional – not everyone wants it<p>The Psychology<p>Research backs the "Rule of 3":<p>1. Cognitive load theory: working memory handles 2-4 items optimally
2. Completion psychology: finishing tasks releases dopamine, builds momentum
3. Decision fatigue: fewer choices = better decisions<p>When you complete 3 meaningful tasks vs. half-finishing 15 random ones, the psychological difference is profound.<p>Development Journey<p>Started as a personal productivity experiment after that Reddit thread. Friends noticed I seemed less stressed, more focused. Built MVP in Flutter because:<p>1. Cross-platform with single codebase
2. Native performance for smooth UX
3. Rich ecosystem for device integrations<p>Beta tested with the original Reddit community who kept saying "don't add more features, keep it simple." That feedback shaped the entire product philosophy.<p>Business Model<p>1. Freemium: Core features free forever
2. Premium: Advanced calendar features, themes
3. No subscription trap – one-time purchase philosophy
4.Privacy-first monetization (no data selling)<p>What's Next<p>Currently live on iOS App Store, Android coming soon. Considering:<p>1. Apple Watch companion (because glancing at 3 tasks makes sense)
2. Simple widget for home screen
3. Export functionality for data portability<p>Not considering:<p>1. Web version (mobile context is key)
2. Team features (individual focus is the point)
3. AI integration (human intention > algorithmic suggestions)<p>Metrics That Matter<p>Instead of DAU/MAU, I track:<p>1. Daily completion rate (3/3 tasks)
2. User retention without growth hacking
3. Qualitative feedback about stress reduction<p>Early users report completing more meaningful work while feeling less overwhelmed. That's the real success metric.<p>Try It<p>Available at 3tasksperday.com and iOS App Store. The app is intentionally simple – if you're looking for complex project management, this isn't it. If you want to focus on what truly matters each day, it might be exactly what you need.
Built by a developer who was tired of productivity theater and wanted something that actually works.<p>Questions for HN:<p>What's your experience with productivity app bloat?
Do you think intentional limitation is undervalued in software design?
How do you balance feature requests vs. product focus?
