I would have loved to use the Transferable protocol to export the journal entry, and I probably still could, but for now, it made more sense to bundle it all into a folder and put it in a ShareLink. It really is just a folder with all the stuff in it.

The Shortcuts Gallery in iOS is incredible. Just a ton of make-life-nicer features and no apps required

You can get rich text editing in Rambler as well! You select text and then get the option in the same menu that lets you copy and paste. Go nuts :)

AI-powered bullet points! (Optional, as always) Automatically generate summaries of your rambles, or edit them to be whatever you want.
Great for quickly reviewing what you talked about, or creating your own custom summary.

Using the picker is simple. This is a nice way to incorporate this. The trick is supporting all of the different ways that a journaling suggestion can be accessed. You can see all the different kinds here: developer.apple.com/documentatio...

The chart on the left is just the funniest thing you could do to introduce state-of-the-art AI. How do those numbers line up?

Okay, I'm digging the new look of the OS (also, sneak peak at what's coming in a new release of my 3D scanner, turntable mode!) You'll want to expand the images to see the whole thing. #WWDC25

OMGosh, visionOS widgets just work out of the box. I loaded up my Pearl app via the iPad app on the Vision Pro, and the widgets appeared. And the on-device AI via MLX is working too! Beautiful. Made sure to make my ridiculous affirmations about eggs. #WWDC25

Core to the clock movement is making the hands conform to a RealityKit component system. Here is the code as a gist as an example of the secret sauce behind the app.

I separated out the hands, or added my own hands, and made it so that they always coincide with the user's exact time and timezone.
It was tedious work, but honestly, pretty intoxicating to dive in and tinker and perfect.

I got 3D models from artists and I credit them in the app as appropriate with the artists' terms and such. Then, I adjusted the models with clock faces: the Steampunk Clock, the Grandfather Clocks, and the Wooden Desk Clock.
