Folded, you see the ships in the Port of Hamburg. Unfold, and the whole Elbe opens up. 🚢 Franzbrötchen now supports iPhone Duo!

Yesterday I found out that @mertbulan.com has recently launched the app that I wanted to build for over two years now but never found the time 😄 A simple routine app with iCloud Sharing for coordinating morning routines with my wife. I love it! Go check it out: apps.apple.com/de/app/chores-...

I also had similar observations related to "engineer's disease" and "brain-rotting drug" but didn't know that there were already defined terms for those behaviours.

If you had invested in European stocks instead of the S&P 500 at the beginning of the year, you would have earned about 15% more in gains.

I've been investing in the S&P 500 ETF for the past seven years, but I stopped this year. The main reason I invest in ETFs is for diversification. However, when nearly 40% of the index's value is concentrated in just the top 10 companies, it no longer feels diversified enough for me.

If you follow the mainstream media, you'll often hear comparisons of GDP growth between the U.S. and Germany, usually framed as Germany "falling behind." That narrative misses the point: the issue isn't a lack of productivity, but rather that Germans generally choose to work fewer hours.

It's my birthday, but today *you* get the presents! Introducing "Beans", a CLI-based, flat-file issue tracker designed for humans and their robot friends. 🫘 Track your work right in your repo, using the CLI. And if you work with coding agents, supercharge them with a full picture of your project!

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. punkt-am-ende.work/2025/12/03/f...

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. mertbulan.com/2025/12/01/w...

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. :)
