Opened my door and was confronted with yet another person telling me to upgrade my internet "or else."
The German Verbraucherzentrale is aware of this. I hope something gets done. It feels bad to be harassed in your own home.

Yesterday evening I painted this. It's the first proper artwork I've worked on in years.

One of my goals this year is to stop letting perfectionism get in my way. So this little piece is my first foray in that direction. And even though I'm not entirely happy with it, I am happy that it exists.

Did I miss running? Not really. Will I keep doing it every other day? Unfortunately.

She also congratulated me on the lack of hair loss at 36. Shoutout to my genes! (If you're listening to this as a podcast: I wrote genes not jeans. Don't be confused. (Shoutout to Sydney Sweeney!))

I SWEAR I'm not especially small, it's just that @teesche is very tall.

I even showered for this event!

Spent some snowstorm quality time with my children.

Ugh, I hate how much horizontal space the new @figma.com sidebar wastes.

It's a bit foggy today.

Happy 100 days of journaling streak to me!

ngl, Gemini 3 Pro Nano Banana is impressive.

I also added this little friend to the header. Cute, isn't it?

Zeitgeist is available on the App Store. Give it a try, I think you might like it.

But that's not all! Zeitgeist's whole purpose is to make journaling quick and fun. You can now long press on a reminder notification and jot down a quick entry without even opening the app. 🚀

That made me redesign the old calendar view. It's Stats now! Look at that mood graph! And even a map that shows all the places you've been. Incredible.

All the people are talking about it. They call Zeitgeist the most innovative journaling app of our generation.

I added a few new features recently. For example: Mood tracking! Track how you feel and get better insights into what makes or breaks your day.

Happy internet meme number MRR day to me

In Zeitgeist, the journaling app where writing entries feels like posting on social media but without all the other people, you can now add notes about the people you mention in your entries. Want to remember allergies, gift ideas, likes, dislikes? Put them in there!

Still a bit rough around the edges, but I’ve got a first version of State of Mind tracking working in Zeitgeist.

It’s one of the most requested features.

Threads introduced posts that only show up for 24 hours. They're using the ghost metaphor to explain it and I tried my hand at topical marketing.

What if your habit tracker just showed tally marks and none of the other useless stuff nobody cares about?
