+![CoreHour - Time Management Tool](/images/projects/corehour.png)
+
+## Introduction
+
+**CoreHour** helps you discover your peak productivity hours and build work habits that actually stick. Built for indie hackers, makers, and anyone who wants to make every hour count.
+
+I created this project with [Carol Hsiao](https://carolhsiao.webflow.io/) as part of **Aburi Studio**'s financial independence toolkit. CoreHour bridges the gap between time and money - helping you understand which hours generate the most value.
+
+## Demo & Source Code
+
+CoreHour is live and ready to use:
+
+- **Website:** [corehour.app](https://corehour.app)
+- **Source Code:** Private (part of Aburi Studio products)
+
+## Why We Built CoreHour
+
+As indie makers building our own products, we struggled with a common problem: **not all hours are created equal**.
+
+Some hours we're incredibly productive - shipping features, solving hard problems, making real progress. Other hours? We're just going through the motions.
+
+Traditional time trackers tell you *how long* you worked. But they don't tell you:
+- **When** you're most productive
+- **What** work generates the most value
+- **How** to align your time with your financial goals
+
+That's why we built CoreHour - to help you work smarter, not just longer.
+
+## Key Features
+
+### Smart Time Tracking
+Automatic detection of your most productive hours. CoreHour learns your patterns and helps you schedule deep work when you're at your best.
+
+### Goal-Oriented Design
+Align daily tasks with long-term objectives. See how today's work connects to your bigger vision.
+
+### Cashflow Integration
+Connect time to revenue for better project decisions. Understand which activities actually move the needle on your financial independence journey.
+
+### Habit Building
+Sustainable routines backed by your actual productivity data. Build habits based on evidence, not guesswork.
+
+## The Philosophy Behind CoreHour
+
+CoreHour is built on several key principles:
+
+### Quality Over Quantity
+It's not about working more hours - it's about making the hours you work count. We focus on productive output, not time logged.
+
+### Energy Management
+Your energy fluctuates throughout the day. CoreHour helps you identify when you're naturally most focused so you can schedule accordingly.
+
+### Value-Based Time Tracking
+Not all tasks are equal. CoreHour helps you identify high-value activities and eliminate time sinks.
+
+### Sustainable Productivity
+Burnout is real. CoreHour encourages sustainable work patterns that you can maintain long-term.
+
+## How CoreHour Works
+
+1. **Track Your Time:** Log what you're working on throughout the day
+2. **Discover Patterns:** CoreHour analyzes when you're most productive
+3. **Align With Goals:** Connect daily tasks to your long-term objectives
+4. **Optimize Schedule:** Schedule deep work during your peak hours
+5. **Track Value:** See which activities contribute most to your goals
+
+## Part of the Aburi Studio Ecosystem
+
+CoreHour is designed to work seamlessly with our other financial independence tools:
+
+- **FireFree:** Calculate your path to financial independence
+- **DailyPay:** Monitor daily spending and income
+- **CoreHour:** Optimize how you spend your time to reach your goals faster
+
+Together, these tools help you:
+- Understand where your time goes
+- See how time connects to income
+- Optimize your path to financial freedom
+
+## Technologies
+
+We built CoreHour with a modern, focused tech stack:
+
+- [Next.js](https://nextjs.org/): React framework for optimal performance
+- [TypeScript](https://www.typescriptlang.org/): Type-safe development
+- [Supabase](https://supabase.com/): Backend and database
+- [Tailwind CSS](https://tailwindcss.com/): Beautiful, responsive UI
+- [Recharts](https://recharts.org/): Data visualization
+- [Vercel](https://vercel.com/): Deployment and hosting
+
+## For Indie Makers and Solopreneurs
+
+CoreHour is specifically designed for people building their own products and businesses:
+
+- **Project-Based Tracking:** Organize time by project, not just task
+- **Revenue Attribution:** See which projects generate income
+- **Focus Sessions:** Built-in Pomodoro timer for deep work
+- **Weekly Reviews:** Reflect on what worked and what didn't
+
+## What Makes CoreHour Different
+
+Unlike traditional time trackers:
+
+- **Goal-Oriented:** Everything ties back to your long-term objectives
+- **Energy-Aware:** Respects your natural productivity rhythms
+- **Value-Focused:** Emphasizes output over input
+- **Independence-Minded:** Built for people pursuing financial freedom

+
+## 專案簡介
+
+**CoreHour** 幫助你發現高峰生產力時段，建立真正持久的工作習慣。專為獨立開發者、創客、和想讓每小時都有價值的人打造。
+
+我與 [Carol Hsiao](https://carolhsiao.webflow.io/) 共同創造了這個專案，作為 **Aburi Studio** 財務獨立工具套件的一部分。CoreHour 連接時間與金錢之間的橋樑——幫助你理解哪些時間創造最多價值。
+
+## Demo & 網站
+
+CoreHour 已上線並可使用：
+
+- **網站：**[corehour.app](https://corehour.app)
+- **原始碼：**私有（Aburi Studio 產品的一部分）
+
+## 為什麼我們要打造 CoreHour
+
+作為打造自己產品的獨立創客，我們遇到一個常見問題：**不是所有時間都具有相同價值**。
+
+有些時段我們超級有生產力——推出功能、解決難題、取得真正進展。其他時段？我們只是在走過場。
+
+傳統的時間追蹤工具告訴你工作了*多久*。但它們不會告訴你：
+- **何時**最有生產力
+- **什麼**工作創造最多價值
+- **如何**讓時間與財務目標對齊
+
+這就是為什麼我們打造 CoreHour——幫助你更聰明地工作，而不只是工作更久。
+
+## 主打功能
+
+### 智慧時間追蹤
+自動偵測你最有生產力的時段。CoreHour 學習你的模式，幫助你在最佳狀態時安排深度工作。
+
+### 目標導向設計
+將日常任務與長期目標對齊。看見今天的工作如何連結到你的更大願景。
+
+### 現金流整合
+連結時間與收入，做出更好的專案決策。了解哪些活動真正推動你的財務獨立旅程。
+
+### 習慣養成
+基於實際生產力數據的可持續例行工作。根據證據而非猜測來建立習慣。
+
+## CoreHour 背後的哲學
+
+CoreHour 建立在幾個關鍵原則上：
+
+### 質量重於數量
+重點不是工作更多小時——而是讓你工作的時間發揮價值。我們專注於生產力產出，而非記錄的時間。
+
+### 能量管理
+你的能量在一天中會波動。CoreHour 幫助你識別自然最專注的時段，讓你相應安排工作。
+
+### 價值導向的時間追蹤
+不是所有任務都同等重要。CoreHour 幫助你識別高價值活動並消除時間黑洞。
+
+### 可持續的生產力
+倦怠是真實存在的。CoreHour 鼓勵可長期維持的可持續工作模式。
+
+## CoreHour 如何運作
+
+1. **追蹤時間：**記錄你一整天在做什麼
+2. **發現模式：**CoreHour 分析你何時最有生產力
+3. **對齊目標：**將日常任務連結到長期目標

+
+這些工具一起幫助你：
+- 了解時間去向
+- 看見時間如何連結到收入
+- 優化通往財務自由的路徑
+
+## 技術架構

+- [Tailwind CSS](https://tailwindcss.com/)：美觀、響應式的 UI
+- [Recharts](https://recharts.org/)：資料視覺化

+## 為獨立創客和個人創業者設計
+
+CoreHour 特別為打造自己產品和事業的人設計：
+
+- **專案導向追蹤：**按專案而非僅任務組織時間
+- **收入歸因：**看見哪些專案產生收入
+- **專注時段：**內建番茄鐘計時器進行深度工作
+- **每週回顧：**反思什麼有效、什麼無效
+
+## CoreHour 的獨特之處
