Answer 1

The following link may help you:
https://forum.ionicframework.com/t/how-to-determine-if-browser-or-app/89149/16

or you can use the following method:

public isDesktop() {
    let platforms = this.plt.platforms();
    if(platforms[0] == "core" || platforms[0] == "mobileweb") {
        return true;
    } else {
        return false;
    }
}

Answer 2

In case anyone is still struggling with this on ionic4/cordova, I solved it using

import {Device} from '@ionic-native/device/ngx'

Just add it into your app.modules and run this.device.platform wherever you need to find out, to give an idea, the output on web and apk from this simple code

console.log(this.platform.platforms());
console.log(this.device.platform);

is this:

Running on web (desktop and mobile)
["android", "phablet", "cordova", "mobile", "hybrid"]
browser

Running android local (apk)
["android", "cordova", "desktop", "hybrid"]
Android

Now I can correctly use the plugins for browser or mobile correctly, in my case is image loading and cropping.
