Ratings and Reviews
Excellent app with a killer feature
This is a great app for family or enterprise use. Great voice quality, flexible options, nice integration with iPhone (and iPad), lovely user interface.
And: After some plowing through Acrobits’ wiki and scratching my head a little, I found it supports external provisioning. That’s wonderful: you can set up simple .xml provisioning profiles on a web server (or even in Dropbox’s public web folder) and give your users a click-link that, when clicked on their iDevice, will automatically set this application up. I’ve encouraged Acrobits to improve the description of how to do this, but if I figured it out you probably can too.
Really great app, and well worth the small amount of money it costs… especially considering the massive savings VoIP brings!
UPDATE: after several years I remain delighted with this app. Call quality, ease of use, iPhone-worthy design... first class stuff.
Developer Response ,
Thank you very much for your kind words!
1 star or 5?
In general, for its capabilities, the app deserves 5 stars. The user interface could be a bit more cleaned up, and settings could use more help text, so that’s about 3 stars.
What infuriatingly wants me to give one star: still no UI adaptation for iPad! Together with a BT headset or handset, it would make an excellent, powerful desk phone/speaker phone. So that deserves one star.
So, a product that could easily be a five star product, will thus only get an average of three.
I paid 20$ and still get ads!!
They now show an icon for a totally different product, a wifi finder permanenty in the title bar! You can't hide it! If you tap it, they want to sell you a subscription! This is absolutely unacceptable for an expensive paid business app!
And now they made the design worse by spacing out the list items so much fewer fit on the screen. This is a productivity-App, not a design piece!
Developer Response ,
we believe that finding a free wifi nearby may be useful, for example when you travel. The small white icon should not be too intrusive, but in case you really don't want to see it anymore, you can hide it by going to Settings -> Preferences -> Controls and setting "Show Wifi Finder" to "off".
