Recently my wife gave birth to our son and I purchased the tinycam pro app to use with my d-link DCS-932L as a baby monitor.
After some tests I was satisfied with the results and decided to buy the app for my wife's google account, so she can monitor our child with her own phone. It was a surprise when I found that google provides no simple way to achieve such a simple task.
My wife has no international credit card, and even if she did I would be reluctant to associate her google account with one, since she's very careless regarding account/password security
What options do I have to install the app on my wife's phone without adding credit card information to her account?
