I have an existing website and I require two versions of a simple app, for Android and Apple mobile phone devices.
The apps function will be to open the website for use by the customer, but I would like the app to do so specifically by performing a background google search for the website by name; then accessing the website firstly via the result google provides, or then, on a search failure, to open the website directly via its internet address.
The apps must not visibly open an external browser, such as chrome, safari or IE/edge, so all search and browser function should invisibly merge with the app itself, with everything happening in the background. The user should just open the app and see the website.
I also require fully annotated source code, so as to allow for minor maintenance as needed.
