What is the best way to make a mobile application with Bitrix?

Question

Mobile development

There is a sophisticated project on the Bitrix corporate portal.
With its specific business logic.
I definitely think it is necessary to use a framework like phonegap.
one). Suggest alternatives please.
2). Is it worth making a separate api for the application, is it possible to do without it.
3) Do I need to host on a separate server, the application is not for the masses, for a narrow circle of people.
The essence of the application is the display of various information with different access settings, public, partially accessible, completely secret, all sorts of user groups, etc.
Editing this data is essentially a form.
No animation, information app.

Answer 1

If there is a corporal on Bitrix, then try to take their standard application and customize its server part, because. it pulls 90% of the interface from the server. You will not be able to change the authorization page and the bottom menu, but you will save a lot of time.

Answer 2

The essence of the application is the display of various information with different access settings, public, partially accessible, completely secret, all sorts of user groups, etc.
Editing this data is essentially a form.
No animation, information app.
For this, the mobile version of the site is enough.
