Still no icon showing up for Tutti on the iPadOS 26 App Store.
Hurts to spend months working on a release and then have this happen. If you work for Apple and/or have any idea how to resolve, I'd appreciate the help <3

What are the deets for the speaker on the iPhone Air. Does it require headphones? I couldn't find anything on Apple's website about it.

So I'm currently vibe coding a new PDF Viewer for Tutti that is built on top of the PDFKit utility classes. GPT-5 is so far doing really well. I've started to settle into a flow: Vibe code a small piece of functionality, and then review the code to find ways to simplify and reduce complexity.

GPT-5 was super impressive this morning and now around lunch time EST it's acting more like GPT-3 and the website is barely responsive. Guessing there is huge demand with the new model being released. Anyone else experiencing the same?

Physicality: the new age of UI
There’s a lot of rumors of a big impending UI redesign from Apple. Let’s imagine what’s (or what could be) next for the design of iPhones, Macs and iPads.

My prediction:
A small circular or rounded rectangle device with a touch screen on both sides. It will feed video/audio context about your life to your OpenAI profile
Easily attach or detach from magnetized clip accessories from your shirt, necklace or wrist. (or slip into pocket)

The io device is mysterious and important – what could it be?
Jony Ive and Sam Altman yesterday released a strong candidate for most frustrating video of the year: promising a completely new concept in AI hardware, but giving very little clue as to what it might be.
I transcribed the video to see whether I could spot any clues, in conjunction with other things the two have said. I think we can draw some pretty safe conclusions about what it’s not – and there are one or two clues about what it is …

Tutti's onboarding flow is coming along nicely! I'm noticing that I really enjoy animating SF Symbols.. Should I animate all of them? 🤩
