Looks like many of those mobile app generators these days:
Seems like most (all?) are making react native apps using expo.
I think you're missing some too. I've been vaguely following and have seen very few that actually seem to have any apps on the app store and those that I found were basic examples.
We’re a bit different than these since our apps are instantly deployed, not deployed through expo. So right after generation, you tap on your app and it loads and is usable, kinda like a webpage.
React native definitely seems to work the best! I think the current generation LLMs have just seen so much js/ts they can just about do anything in those languages.
