• You want a web page to be able to read what apps a user has installed? Really? Do you think this might be a security/privacy problem? I don't know iOS, but on Android, this is not possible. – Simon Commented Jan 3, 2014 at 15:36
• Hi Simon, thanks for that insight. If that is a problem, we need the code without that bit. So only if android, it should show download popup for play store, and for iphone a dwonload for itunes. – Giancarlo Commented Jan 3, 2014 at 15:43

For the iPhone, promoting your app while checking for its existence is possible with Apple's smart app banner, here are the docs.

This is limited to Apple and Safari, but it's a good starting spot.

Otherwise, I used this library and it has worked pretty well out of the box for me so far..
