Apart from this great app, what is the current state of the art in vibe coding iOS apps? Just using Cursor with an open iOS simulator?

On a personal note, I wanted to thank the HN community. I’ve been reading HN since college (for over 15 years now!) and it’s been formative in my development as a software engineer and leader. I don’t pipe up very often, but I visit HN almost every day. Many of the books I read, blogs I frequent, and podcasts I listen to, I found via HN. I think it’s fair to say, if it weren’t for HN, that Bitrig wouldn’t be Bitrig a…

That’s great and I’m glad you feel good here. I think it’s time for you to share what you found over the years on HN with us. Your curated list, if you will.

When I was in middle school I remember a friend lieing that there is “a mobile app to create mobile apps”. I thought it’s an amazing idea, but it was way too early. I love how this hallucination became a reality. Good luck!

Did you just casually built a workout posture tracking and rep counting app? :-)

Anyway, congrats on the launch!!

For some reason I dislike Log-In by Mail. Since this is purely based on iOS devices, log-in with Apple seems to be an obvious and frictionless solution.

It doesn't seem like this is the direction you are going, but this feels like what Siri could become (though I have little faith given the history). With your sunscreen example, I should be able to just ask Siri to do exactly this, and it could tap me in my pocket, show me a custom UI to log periodically and then disappear. Not sure on limitations of APIs on iOS but definitely feels like there is space for a better v…

Maybe this paired with something like App Clips? I don't see them used much these days but could make them more useful.

Would you consider having a way to export work done in this app to be included as part of regular Xcode projects?

I've been working on a project and sometimes when I'm away from my laptop I have ideas I want to try in SwiftUI but only have my phone on me. What I end up doing is just writing my idea in text and then waiting till I'm back at my desk to give it a shot. Being able to spin up a quick prototype and preview it on the go could be cool.

I don't think my dog would enjoy me lugging my laptop on our walks but my phone is no big deal ;).
