@mysk, actually thought that this was turned off on iPhone. 😕
@elefant_peter @mysk Other apps cannot get a list of all installed apps, but there are simple ways to check for specific apps. You can just ask the device if it supports a specific URL scheme for instance (whatsapp:// or sgnl://).
@dhn @elefant_peter Yes, you need to probe the apps one by one. But thanks to Twitter which abused this some time ago, Apple has restricted apps to probe only 50 apps. The 50 apps must be declared in the Info.plist of the iOS submission. So, Loupe can only probe 50 apps. But as you see, they're enough to develop some trends.
