It has a prior login page and then a settings page inside it.
This demo app is here for test an error/issue when developing the app to a real iOS device. It works with Emulators and with a real Android device
The command used is:
$ tns run ios --device device_identifier_name
Using the command below it's working, but I do not have the realtime control (console.log - errors ...)
$ tns run ios --release --device device_identifier_name
UPDATE: the error is no longer present after the update of the system libs
