If you'd like to learn more about my journey and the origins of my Franzbrötchen app, I recommend reading Christian's article (in German). It was my first-ever interview with a journalist, and I thoroughly enjoyed it. Thank you Christian!
Mert Bulan hat die App Franzbrötchen herausgebracht. Er hat Datenschätze gehoben und intuitiv einsehbar gemacht, die zwar verfügbar, aber deswegen nicht verwendbar sind. Mit der App entdeckt er selbst die Stadt und lädt alle ein, sie mit ihm zu entdecken.

City life can be complicated, with information spread across countless sources. That’s why I believe every city needs a City Super App.
In my latest blog post, I share why these apps are the future and how I built my own for Hamburg, Franzbrötchen.

I'm so happy to have finally found "homemade" Panettone!
I first tried it thanks to an Italian colleague who brought one baked by his Nonna, and it was absolutely delicious with the soft and fluffy texture. I've tried store-bought versions before, but none of them came close.

This was my best app launch yet, over 1.000 downloads in Germany! I really wish Apple provided a city-level breakdown so I could see how many came from Hamburg.
My guess is that Hamburg has around 500.000 iPhone users, so there’s still a long way to go. :)

1st Place: A wine shop that serves Glühwein
This is why I built Franzbrötchen, there are ads everywhere, and it's too hard to find the information you actually need.

@albertguillaumes.cat Hey! Can I use your station drawings in my app that I designed for Hamburg? I'm gathering everything related to the city and your drawings would be a perfect fit! I'll definitely mention your name and link to your page.

OpenAI lost about $10 billion last quarter. For comparison, Apple's failed car project had 5.000 workers, ran for 10 years, and lost about the same amount in total.

Custom Product Pages are perfect for Franzbrötchen, but I wish Apple would allow you to add keywords for each custom page instead of limiting you to picking from the existing keyword pool.

Over three years ago, I had an idea for an app but knew little about iOS development. Since then, I've released 9 apps while gathering resources and refining the concept. In the past few months, I've spent 100+ hours building it and just submitted it to the App Store. And the best part? It's free.
