🌟 Why I Built My Own To-Do App

Most to-do apps in the market are too heavy, cluttered with extra features I never use, and often come with advertisements or complicated menus. I just wanted:

• Simple, clean functions for my daily workflow
• A checkmark system that, when ticked, automatically updates the due date for repeating items (e.g., utility payments)
• No distractions, no bloat — just the essentials
• Fast and lightweight enough to install directly on my iPhone without dealing with App Store rules or iOS development tools

I couldn’t find an easy, minimal app that did exactly this… so I built my own.

✨ Features

• Add / edit / delete tasks with due date, priority, and tags
• Repeat schedules, including Bi-weekly
• Offline support via Service Worker — works without network
• Local data persistence in IndexedDB (private to the device/browser)
• Sorting by due date, priority, or smart
• Tag filtering for focused task views
• Floating Add Task button optimized for iPhone standalone mode
• Yellow DO branding and PWA icon

🛠 Technologies Used

• HTML5 for app structure
• CSS3 for styling (mobile-first, yellow theme, responsive layout)
• JavaScript (ES6) for logic and UI updates
• IndexedDB for local task storage
• Service Worker for offline caching and installability
• Web App Manifest for Home Screen install & branding
• GitHub Pages for hosting

🚀 Setup & Configuration

1. Clone this repo

   git clone https://github.com/<your-username>/<your-repo>.git
   cd <your-repo>

2. Customize branding

• Edit manifest.webmanifest → name, short_name, colors, icons
• Replace icons in icons/ folder (192×192, 512×512, maskable)

3. Deploy via GitHub Pages

• In your repo → Settings → Pages → Source: main branch → / (root) folder
• Save → wait for GitHub Pages URL (e.g., https://username.github.io/repo)

4. Access on iPhone

• Open the URL in Safari
• Tap Share → Add to Home Screen
• Launch from the Home Screen icon

💡 Tips

• Data is saved locally — it will not sync across devices.
• To see the latest version after a code update, open the site in Private / Incognito mode first.
• This bypasses the cached Service Worker.
• Once confirmed, reload normally and the update will install in the background.
• You can install multiple versions (e.g., "DO" and "DO Beta") by saving from different URLs or branches.
• Works in any modern browser (Chrome, Firefox, Edge, Safari) on desktop or mobile.
