On local networks it works no problem. But this is simple and therre are plenty of other applications, much cheaper, that do it too. What instead is UNACCEPTABLE is an app that advertises as using the gmail connection... And then it does not work. Not ony this, but the information around are different, and very confusing. In some places it says you need to log in with your computer credentials, in other with your gmail credentials. If you go to their website, they repeat some basic information that obviously work for some but not for others. And they generally ignore everybody else. Think about it, do you want to buy an app that does not do what they advertise, and ignore requests for help.
