I'm not naming any names here, but I was forgotten about! I normally tend to subtly remind people about things we've planned together, but this friend in particular has always been so reliable that I didn't consider it necessary. He apologized profusely, and I... https://marcel.io/dailies/2026-10-08

TIL Martha's Vineyard is an island. Not even a small one. I thought it's… the vineyard of somebody called Martha. I've been wondering for years why so many people go there.

What are your tipps for cleaning the inside display on iPhone Duo? Seems to be… not that easy.

Instead of sleep, which I apparently traded in for hours of coughing, I just drew this on my PHONE in my bed! The future is now.

When I'm really focused on a project I'm invested in, I still have no problem hammering out hours and hours of focused work. One of the core truths about my life is that I feel better when I have something engaging to work on and think about. I love making pro... https://marcel.io/dailies/2026-10-07

I accidentally built an app that lets me voice my comics. Is this… something? This is something, right?

Yes it is, but come to think of it, you wanted to see a search result with portrait and landscape screenshots, right? I don't know another app that mixed them, sorry.

I tend to get milia on my chest. The aesthetician didn't know why that would ever happen and made me feel like some weird edge case of a human being, but getting my face smushed for 50 minutes made me forget that affront pretty quickly. This was a nice experi... https://marcel.io/dailies/2026-10-06

The guy at the bakery asked me about the Duo. This hasn't happened since the iPhone 5.

I like spelunking in the weird corners of the internet where people still discuss whether the Covid vaccines gave us all the ability to wirelessly communicate with Microsoft's servers. It's fascinating to see people still stuck on a topic that everyone else ha... https://marcel.io/dailies/2026-10-05

Watch Unlock on the Duo feels like FaceID. It's SO quick! Solves the issue of missing FaceID for me completely.

Look at how quick Watch Unlock is on iPhone Duo. It's basically instantaneous.

It's so weird that holding the iPhone Duo unfolded in portrait orientation takes landscape pictures and videos and the other way around. I get it but it feels wrong.

OMG, USB-C Apple Pencil plus Procreate Pocket on iPhone Duo is THE DREAM. So good!

This isn’t even the first time this has happened. I get that Jony Ive seems to think his life’s mission is to remove every button on Earth, but ugh. Then again, I bet Jony Ive doesn’t have a pet. They’re not clean enough to keep in a featureless white box. An... https://marcel.io/dailies/2026-10-04

First impression of the iPhone Duo: I expected to like it a lot but I think I might love it. It's everything I wanted it to be and more.

First iPhone Duo hot take: Nobody will ever use it in half folded book style mode. Doesn't make any sense to hold it like that.

Zeitgeist 2.0 is out now, and I think it's the best journaling app around. Let me show you why. 🧵

Love this Thread with these little feature(videos)! 🫰 Already used Zeitgeist 1.0 last year for quite some time and liked it a lot - will definitely try this big update as well. Great work 🙌

Anna and I had one of our fantastic “let’s do a bunch of neat little activities around the city” days. I’ve been back in Hamburg for more than two years now, and I’ve only just gotten around to climbing up the bunker. When I first lived in Hamburg, the structu... https://marcel.io/dailies/2026-10-03

Slept well. Time outdoors. Saw friends. Little tags for the things that make a day good… or not, so you can spot them later.

This is why I built it. Most days aren't special enough to remember, and they're exactly the ones I want to keep.

And the rest of your day fills itself in: photos, sleep, your calendar, your runs, the places you went. You write one line, and Zeitgeist adds the rest.

Most journaling apps want an essay. Zeitgeist wants a quick note. Who you were with, where you were, how it felt, done.

You don't need to sit down at night and remember everything. Write a line when something happens and keep going.

People are reacting to apps not being updated for the iPhone Duo yet as if we didn't go through the exact same thing with the iPhone X.

I wish I’d started planning my retirement fund earlier. For most of my 20s, I knew I should do something beyond the statutory pension insurance, but I never found the courage to learn about my options and actually invest my (kind of) hard-earned money. I didn’... https://marcel.io/dailies/2026-10-02
