What type of application, cross-platform or native, should I choose for a travel guide?

Question

Mobile development

It is necessary to develop an application, the main of which will be an online store of excursions. But in addition, you will need to implement such things as:
1. Augmented reality function (the user points the camera at an object in the real world (for example, a museum, the application recognizes the object and gives help on it)
2. Pushes based on the user's location
Each application is a separate service It

is, of course, easier and cheaper to make an online store of excursions cross-platform as a web application, but when functions related to the use of a camera and gps-tracking were added to the project, we thought hard about what to choose? application, we will not be able to correctly control the functions of the phone (camera, gps)?
