Wifi finder paid subscription

Should notify the user in the app that it is a paid subscription at the point of activation. I could not locate any notification in the app or on acrobits Softphone website- did I miss it?

Also what’s the relationship with Facebook there?

Developer Response ,

The exact terms of subscription are described in the app, in the app description, in the linked "Terms of Use" document and iOS asks confirmation twice before the subscription is activated. We will be adding translations to more languages, but I don't see much space for improvement in making it more clear.

As for Facebook - there is no relationship. Some of the venues with wifi hotspots have Facebook pages and if they do, we show links to them.

Way better than whats out there

I will keep it short and simple by saying that this software is all you need. My voip provider wasnt in the preconfigured list by Acrobits, but as I am techinical I knew the fact that this softphone should be able to work with any voip provider(PENNYTEL in my case) as long as you have a domain. I popped in all the details and it was all ready to rock and roll. It took me a while to get used to software and all the options it had, but after 10 mins I was good to go. In addition my bluetooth headset works quite well with it and ofcourse the call connects quite quickly. I guess its worth the heafty price tag next to it. These guys have done a bit of work :)
