About Apps detect

That depends on how the app browser identifies itself. mobble simply inspects the user agent (https://whatsmyuseragent.com/WhatsAUserAgent). If there are clear differences in the app useragent then yes it can be detected.

Visit: https://demo.mobiledetect.net/ from both browsers and make a note of the user agent string, see if there are any obvious differences. If there are then we might be able to use some hidden features of mobile detect (upon which mobble is based) to create some code that works.
