A few weeks ago, the Salzburger Nachrichten ran a story about my fuel price app. I woke up to more messages than I could count. Readers had either newly discovered the app, existing users asked what was coming next, and others simply wanted to say thanks. It was one of those mornings that reminds you why you build things in the first place.
The article, Er hat die Spritpreise genau im Blick from April 14, 2026, is embedded below for reference.
At that point, we were talking about my apps Spritpreise Österreich and Spritpreise Deutschland. I also mentioned that a unified European app, Petroly, was coming. I said May as a rough target. I was trying to be realistic.
It turns out I was too conservative.
It is not even May yet, and Petroly is already live on both the App Store and Play Store.
What I did not fully anticipate was how much Agentic Software Development would accelerate everything. The way I build has changed fundamentally over the past six months. I am not just writing less boilerplate. I am collaborating with AI on architecture, exploring different implementation approaches, taking care of my backends, handling localization across eight languages, preparing App Store metadata, and even automating submissions, just to name a few.
Tasks that used to take days now take hours. Ideas that once felt like "next quarter" become "tonight."
The result is that Petroly launched ahead of even my most optimistic timeline. It is not just an iOS release. Android shipped alongside it. The app supports eight languages, includes a full website, subscription tiers, and a computation-heavy routing feature that highlights fuel stops along your journey.
This is the kind of scope I would previously have spread across many weekends and late nights.
From the inside, the experience is interesting. The work has not disappeared. The ceiling has simply moved. What one person can realistically build in a short amount of time has increased dramatically. The decisions are still mine. Product direction, design, and the judgment of when something is good enough still matter just as much.
What has changed is the distance between an idea and a working product. That gap has become much smaller. And that is something I genuinely enjoy.
If you want to track fuel prices or plan routes around cheaper stops, Petroly is now available on iOS and Android. The app is free to download.
