With a simple command we can issue a mobile build from this code base.
Since I don't have a Mac with me at the moment, I've only built the Android version (APK).
The APK is currently being built targeting Android SDK 29. However, since it has a minSdkVersion parameter of 21, any Android 5.0+ should be able to run the app.
If you wish to build for iOS, simply follow the steps in the Quasar documentation.
