Fantastic!
This is the only fax app I’ve tried so I can’t compare it with the functionality of any others. At this point I see no reason to try any others! It is very easy to use on the iPhone or your MacBook. I’ve used it for over a year on my phone with no issues. I just recently bought a MacBook Pro and was having some issues getting the accounts on both devices to link. This ultimately was a training issue on my part and not an app issue. Customer support via email was phenomenal. Quick responses to my emails and they walked me through the set up to get it working on the computer. Very pleased all around!!
