A PWA might be well suited to your needs. Even Apple's restrictive model leaves plenty of room to build useful apps especially if they are designed to connect to a backend (like the ones in the post).
I have used PWAs and online web apps for a lot of my vibe coded tools, but sometimes you just want/need native features and performance.
