It’s a fair assumption. The React part is more about copying JSX and other React concepts (declarative UI etc) but it all boils down to native binaries. The toolchain is also pretty nice. It does hot reloading so you don’t have to recompile the app while building locally. The downside is you get less for free compared to SwiftUI. But SwiftUI also has many footguns and bugs. No free lunch!
I bought and tried to use the MP02 as a daily driver. Quite different from where Punkt is heading now. The industrial design is gorgeous, but the software was pretty bad (laggy, unintuitive navigation - Android on such a low powered chip was a bad choice). I can guess why, but it baffles me they didn't jump on the growing demand for dumbphones. If they had just released an MP03 with identical form factor but improved battery life, latency and screen improvements, I would have bought one in a heartbeat.
HTMX is a great choice for an app that only needs forms, validation and partial template rendering, though CSS view transitions are making partials less relevant for server side web applications.
For things with heavy interaction (drag and drop, chat etc.), I find the code to make it work with HTMX is just too clumsy to work with as a mental model.
