Hi,  
I have run the web app on Browser platform an used the localhost ip to run the app in the mobile browser on the smartphone but it does not detect [platform.is](http://platform.is)('mobileweb) it always gives me false.

Any ideas on how to detect if the web app is running on mobile browser on a tablet ore on a smartphone?

You can use device native plugin. I guess you can check with this.device.platform == “browser”.
