I developed 12 mobile apps so far. I have experience in developing native Apps for Android in Kotlin and Java.
I use the "native approach" when i have to build voice systems with SIP stacks. I do not have much experience in building native iOS apps.

If you need a standard app (which does not require "native" access to the underlying hardware) I propose to use Ionic or Flutter.
So you will end up with an Android and iOS app.

Attention: I'm not a UX or graphic designer. :-). So please provide either the finished design or hire an additional UX designer.
