I have installed it on my iPad, and find it to be the perfect app for that platform. It integrates well with all of my cloud storage apps, as well as eFax -- and probably with more apps that I haven't even tried out yet. It really is one of the best apps that I have ever seen. And to top it off, their customer support is very proactive. I got an email from their CEO shortly after signing up, and then another a few days later from an account representative. There was no pressure to buy anything, just a friendly follow-up. Again, this app is a must-have for anyone running a paperless practice.
