i just saw this: https://creolabs.com/ Creolabs, a new player on the IDE market.
Seems interesting, but not clear for me exactly what language they use. Did not dive in it to deep to check.
But the pricing seems also nice and after one year of paying 99$/year, it stays active (no community backdrop) so one can still build closed standalones.
For now only iOS is supported, but Android will follow. Also no XCode seems to be necessary.
For the one who is interested. I'll stick to LC
