Hi everyone! 👋 I built Sigma Habit because I was hitting serious subscription fatigue with existing habit trackers. Most modern apps force you to create an account, sync your personal daily routines to a cloud server, and lock basic features like streaks or data exports behind a hefty $40+/year paywall. I wanted the exact opposite: something that feels as powerful as a native app but is as simple and private as a piece of paper. With Sigma Habit, there are no sign-ups, no tracking, and zero friction. You just open the link and start tracking. Your data never leaves your device's browser local storage, and it even works completely offline. What started as a basic tracking grid quickly evolved. I wanted to make progress highly visual and rewarding, so I built in a GitHub-style yearly heatmap, daily completion bar graphs, and even an ink-friendly, one-click printable PDF export for anyone who likes having a physical chart on their desk or fridge. It is 100% free and unlimited. I’d love to hear your thoughts, feedback, and features you'd like to see next! Let me know what you think! 🚀
