Laetus

I built an app to explore personal luck ... For a long time I was fascinated by the idea of luck. Not in the mystical sense, but in the statistical one.

Some people seem to encounter fortunate outcomes more often than others. Of course randomness is random but our lives contain thousands of small chance events. I started wondering: if you observe enough of them, do patterns begin to appear?

Instead of spending money on real lottery tickets, I built a system that creates harmless virtual lottery events. No real betting, no real prizes: just simulations.

The idea is simple: generate many small “luck events”, observe outcomes, and see how probability behaves over time for a particular person.

This became a project called Laetus. What it does:

• simulate virtual bets across ~50 real-world lottery formats
• generate number combinations from drawings, text, or symbols
• track results and analyze patterns over time
• explore where your “luck” statistically appears strongest

The goal is exploring probability in a personal way. Technically it turned into a full solo project: backend + data pipeline; cross-platform mobile apps; web version; analytics and visualization.

Most of it was built with AI-assisted development, which helped a lot with speed. But architecture, logic and decisions were still entirely human. I'm curious what this community thinks about the concept.

Do you think people would be interested in exploring luck statistically, rather than chasing it through gambling?
