I just started using a Skype similar application on my Android. The application automatically imports your contacts and facebook friends to have them visible as callable contacts in the application.
However, to call them without charge, it's required that they have the application as well, same as with Skype. Therefore there is an invite feature in the application, a button that says "Invite friends to call for free" (terrible button caption, I know...).
When you click that you open a dialogue that looks like this:
And here my issue begins. Personally I got off put by the description of the action. To me it seams very unclear whether clicking any of the buttons will move me to a new view to make selections of which friends I want to invite or whether the application will fire up a workflow that sends invitations too all of my contacts, something that I'm not that keen on.
My question is if this would be considered an efficient communication to users to invite new users? Or if it could actually hinder conversion rate, seeing as I as a user was not to keen clicking either of the buttons in fear of sending out a mass spam messages.
Never mind what the actions actually does, since knowing that erases the problem.
