Hey fellow devs, Ever had a brilliant code idea while stuck in traffic? Or spotted a bug in your project during your morning coffee run? Yeah, me too. That's why I built CodeReader. Born from a coding itch (and a broken leg), CodeReader isn't just another GitHub client. It's the tool I wished I had when I couldn't reach my laptop. What's in it for you? 1. Capture ideas on the fly: Jot down those "aha!" moments before they vanish. No more napkin scribbles or forgotten strokes of genius. 2. Read code comfortably on your phone: Customize the display to your liking. Because squinting at tiny code on a small screen sucks. 3. Multi-language support: Whether you're into Python, Java, Rust, or that niche language you're tinkering with - we've got you covered. Why bother? - For when inspiration strikes at odd hours - To make use of those "in-between" moments - For quick code reviews without lugging around your laptop Look, I'm not going to claim CodeReader will revolutionize your life or make you the next tech billionaire. It's simply a tool that might make your coding life a bit easier and more flexible. Want to give it a shot? Grab CodeReader and see if it fits into your workflow. If it doesn't, no hard feelings - I'd love to hear how we could make it better for you. Happy coding! CodeReader: Your Pocket Coding Companion
