The LNhealth app is similar to your desired workflow. It runs scripts written in Scheme that define the pages in the app. When developing for Android I can just push a change to the script (using the Android Debug Bridge - adb) and do not need to recompile the app itself. It makes for a much faster development cycle.
Yes, this is quite true. When developing mobile apps for global health projects they are typically in Android. We are working with research teams on the other side of the planet and it is handy to send them a Windows version of an app which they can easily run without needing to install each time on a tablet or phone.
