We did. The only "hiccup" was that if people wanted to deactivate the notifications from the iPhone app, they have to reboot their phone for it to work. I actually tested this out myself. But fairly simple resolution.
There is also now an Android app. Not sure if you need the latest version of the mobile plug-in for it to work. But there are a few rough edges on that one. And I can't really confirm or test any of them because we don't officially support Android so I don't have access to one.
