Like that it remembers where I was in filling in the forms. Filling in was a little awkward on the government forms I was working with. Would help to have a built in tracking mechanism to determine progress.

I was pleased to find the AIR realty forms on your site. We're trying to sublet our space in a commercial building and our landlord insisted on using the AIR forms

I hate when I fill a pdf, then have to log in, and mistype my password, so by the time I've logged in I've lost ALL my work. Otherwise, it works flawlessly

I was very pleased to find most of the forms I needed for filing taxes in pre-fillable forms that I could complete on my PC. And then you guys keep them and allow templates. Wow, very helpful

Seems ideal for filling Apps. Better than Acrobat Pro. While I have only played in the app for about 15 minutes, I very much like the tools provided for completing forms. In fact, they are superior (for the purpose of form completion) to those available in Adobe Acrobat Professional. They are far more intuitive. Once I get more time in, I will likely increase my rating to five stars.

I'm computer illiterate and even I could easily use this It saved me time and money, thank you :) Easy to use and easy to understand format, it made me feel like a pro lol, and I love the feature of being able to download your copies to your computer in either a PDF or a Word file, personally I dislike PDF files but if you have to send or receive them this is the perfect tool to do it with. Have already recommended it to several friends and family.
