It has a very good UX designer and I've developed multiple commercial Qt/QML mobile applications previously.
I think the economics make sense with the following assumptions:
* The startup doesn't have the resources to build for two platforms natively (yet).
* The developer(s) can get their hands dirty and "go native" on either platform when needed.
Users know. That's why most of these apps die within 1-2 years.
Have you used any airline app? Have you used any "cross platform" bank app?
I've actually switched banks because i preferred the one with the better mobile app. A bad app just shows how outdated they are.
Not saying there's no demand for building such apps, businesses clearly don't care (yet). When they start losing business they'll have to care.
I think cross-platform apps are commonly misapplied and really only make economic sense with the appropriate assumptions. Once a company has the necessary resources they should go native and go all in on platform conformity.
But for many folks, that's not a feasible place to start from.
