Mattioli.OS

“We don’t rise to the level of our goals. We fall to the level of our systems.” — James Clear

Let’s be honest: most productivity apps are… too much. Too complex, too rigid, or simply too expensive for what they offer. I spent years jumping from Notion to Todoist, from calendar appointments to Excel sheets, seeking the “perfect system”.

Spoiler: it didn’t exist. So I decided to build it.

Introducing Mattioli.OS (formerly known as Habit Tracker), an open-source personal operating system designed for those who want to master their discipline, own 100% of their data, and track their personal growth.

🧘 The Philosophy: Why Another Habit Tracker?

When I started designing Mattioli.OS, I had three non-negotiable principles in mind that were missing in commercial solutions:

Friction is the Enemy: If it takes more than 2 seconds to log a habit, you won’t do it. The interface must be immediate.
Absolute Privacy: My habit data is personal. I don’t want it sold or analyzed by third parties. With this system, the database is mine (on Supabase) and the code is transparent.
Aesthetics Matter: If an app is ugly, you won’t use it. I aimed for a modern, dark, responsive design that is a pleasure to look at every day.

💎 Key Features

What makes Mattioli.OS different from a simple spreadsheet?

1. Integrated AI Coach 🤖

It’s not just a passive tracker. I integrated an AI Coach that analyzes your weekly data. If it sees you skipped the gym for 3 days in a row, it doesn’t send a generic notification. It asks you why, analyzes patterns, and suggests strategies based on your historical data to get you back on track.

2. Advanced Statistics 📊

Numbers don’t lie. The system generates GitHub-style heatmaps to visualize your annual consistency at a glance. You can see exactly which months you were most productive and correlate data to understand what works for you. But that’s not all; there are dedicated statistics pages for daily habits as well as for macro goals (long term).

3. Total Management (The “Second Brain”) 🧠

Beyond habits, Mattioli.OS manages:

Long-Term Vision: Define your annual goals and break them down into daily actions.
Task Management: An integrated Todo system that communicates with your habits.

🛠 Tech Stack

For the developers out there, here’s what’s under the hood. I chose a modern and performant stack to ensure speed and scalability:

Frontend: React (Vite) for a lightning-fast user experience.
Backend & Database: Supabase (PostgreSQL). Powerful, scalable, and with Row Level Security for maximum security.
Styling: TailwindCSS. For a rapid and consistent design system.
State Management: React Query (TanStack Query). To manage server-state synchronization without headaches.
Hosting: GitHub Pages (Frontend).

🔮 The Future

Mattioli.OS is a living project. I am constantly working to improve it. Upcoming features include deeper integration with external calendars and an even more customizable dashboard.

If you are a developer or a productivity enthusiast, I invite you to try the project. It’s open-source, so you can fork it, modify it, and adapt it to your needs.
