## What is The 50 Day?

Do you want to change yourself through self‑discipline?
The 50 Day App is a habit‑forming tool based on the world‑famous Project 50 challenge. It helps you track progress, develop healthy habits, and achieve your personal goals. Join The 50 Day now and start your transformation!
Effortless One-Tap Check-In
The app features a simple, intuitive interface that lets you record tasks with a single tap. By eliminating tedious operations, the clean design ensures you focus on your habits rather than the UI.

Visual Progress with Heat-Maps
Track your consistency through a dynamic heat-map. It displays daily streaks and highlights gaps, providing immediate visual feedback and the motivation needed to keep your chain unbroken.

Personal Challenge Archive
Your challenge archive stores every completed journey. Review past achievements and habit patterns to stay motivated by seeing exactly how far you have come. It acts as a personal journal of your evolution.

Global Accessibility & Themes
The app supports English and Chinese to cater to a global audience. With Light and Dark mode switching, the experience remains comfortable for your eyes in any environment, day or night.

Seamless Desktop Widget
The desktop widget places your daily check-in right on your home screen. View today’s task and progress bar at a glance, and punch in without even opening the full app.

Full Customization
Tailor the experience to your life. Modify start times, select specific items to track, and set your target day count. Whether you aim for a strict 50-day sprint or a flexible pace, the app adapts to you.

Scientific Habit Formation
Consistent daily actions build neural pathways that reinforce behavior. The 50 Day App leverages this by creating a visible streak that your brain associates with success, encouraging long-term commitment.

Minimalist, Frictionless Design
We respect your time. No long forms or complex menus—just a clear daily task and a single confirmation button. This approach helps you stay committed without feeling overwhelmed.

Detailed Statistics
Your data is stored securely and presented in easy‑to‑read metrics. Track total days completed, your longest streak, and your goal percentage to get a clear picture of your growth.

Flexible Item Editor
Whether tracking exercise, meditation, or reading, define the tasks that matter to you. The flexible editor adapts to any habit you wish to cultivate during your challenge.

Smart Reminders
The reminder system is fully customizable. Choose the exact hour that fits your routine to stay on track, with secondary alerts available for missed days.

### 4/5 — 希望可以设置移除每日感悟

*2026-04-14*

例如习惯在手记上写日记，可不可以设置将每日感悟变成一个任务，而不是一个输入框呢？

**Developer response:** 哈罗 你的需求我们已经记录啦，我们会仔细考虑增加这个设置的，感谢支持呀

### 1/5 — 什么情况

*2025-06-13*

怎么记录都看不见了啊？？？，还重新刷新了天数

**Developer response:** 请问是经过什么操作，导致这样的结果呢，比如更新或者卸载重装或者打开了什么功能

### 3/5 — 界面功能太少

*2025-06-05*

没有皮肤主题，小组件就是大白底很难看，没有图标美化，功能太少，就这还收费这么多，还有小组件显示有时候有问题，总之还有很大改进空间，希望开发者能听取建议！

### 5/5 — 一些小建议

*2025-04-09*

1. 希望开发个可以拍照上传图片的功能，有时候，日记写在本子上了，不想再打字了，可以直接拍个照上传到今日感悟。

2. 可以自定义天数。

3. 设置登录账号，然后可以多设备登录，同步数据 ，让手机和平板使用更方便。

以上是一些建议，给个好评支持，希望可以早日完善这些功能。谢谢！
我又来评价了！40天过去了！什么时候可以有这些功能啊作者大大，非常需要可以上传图片的功能！！怎么可以联系到作者啊，有个很重要的事，！！

**Developer response:** 感谢你如此用心的建议和支持鼓励。上传图片在更新计划中啦，自定义天数下个版本就上线，同步功能之后也会跟上的，再次感谢呀

哈咯，感谢你一直在使用哦，我们最近更新了很多实用的功能哦，您说的我们也在计划中啦，只是要内部评审一下优先级，征求更多用户的优先级，然后去确定先后顺序的。您提到的三个功能，我们已经实现了第二个啦，其他的也会在路上的，想要快速联系我们，可以通过邮箱help@yelatte.com。期待您的联系呀

### 5/5 — 产品一直在优化进步

*2025-04-04*

感觉产品一直在更新 迭代 比之前好用了很了 创作者也比较用心

**Developer response:** 下个版本就支持啦

### 5/5 — iCloud同步

*2025-03-20*

iPhone和iPad为什么不能同步，请改进一下

### 4/5 — 棒

*2025-03-12*

还不错的 希望能有感悟导出的功能和按日期展示打卡的视图

### 5/5 — 用得很开心但有点建议

*2025-03-10*

1.对我个人而言，新版本之前的“今日感悟”输入更好用，可以随时翻看前面的；现在这个版本既不能随时看到前面的，新输入的内容该被遮挡还是被遮挡，还带着两个累赘不美观的按钮，非常容易误触
2.建议增设专门的“今日感悟”导出功能
3.如果有图片打卡就更好了

### 5/5 — 好用！期待50天之后

*2025-03-09*

一直在更新新功能！加油

**Developer response:** 看到这条信息如沐春风啦，我们会再接再厉的！

### 5/5 — 希望可以在每项挑战下自定义上传图片，每做完一项任务就可以拍照上传作为记录，会更有成就感！（比如我运动了一小时，可以上传我运动后的自拍记录或者手表上的运动记录，我觉得会很有成就感！）感恩！

*2025-03-08*

使用非常满意！

**Developer response:** 好滴！感谢建议 在我们的更新计划中啦
