I had no idea what my Net Worth was. So I built an app.

Watched a YouTube video, when it clicked

It was November 2025, and I was watching a video from Nischa on YouTube. She talks about money - good habits, the boring-but-important stuff - and I liked her for being honest about it. I studied finance back in secondary school, so this was familiar ground.

Then a simple question landed: what is my Net Worth?

It hit harder than it should have, because I genuinely didn’t know the number. I had some cash, a few bank accounts, savings scattered here and there, a pension, a couple of investments. But I had never added it all up. I did once, years ago, in a spreadsheet - and then I lost the file somewhere.

I knew what I didn’t want

So I started thinking about how to actually keep track. I knew what I didn’t want. I didn’t want a budgeting app; I’d tried that before. I’d also kept a spreadsheet of my living expenses for more than ten years, and eventually I just got fed up with it. Categorising every coffee was never the point.

The two numbers I actually wanted

What I wanted was quieter. One number I could check now and then. And next to it, a second number: how long my money would actually cover me if things went wrong - my Financial Runway.

One currency, no head math

There was one more wrinkle. My money sits in a few different currencies, and I didn’t want to do the conversion in my head every time. I wanted to see everything in Hungarian Forint, the currency I think in, without the mental math.

So I started building

None of the tools I knew did that calmly. So I started building one.

I showed it to my wife early, because I wanted this to be something we started together - a shared, honest look at where we stand.

That’s the whole motivation. I didn’t build this to make anyone rich. I built it because not knowing felt worse than any number could.

If you’ve never sat down and worked out your own number, that’s genuinely fine - most people never have. But it’s a quiet, good feeling when you finally do.
