Very usable It was easy to get started and the options were not too hard to locate erasing is only left and right, the replace text field is not easy to use and it could be easier to just email a copy of a doc

Love it I love it and have recommended it to friends and collegues. Love the ability to change forms around and manipulate the forms to move entire sections around and still keep things neat and professional looking. The dashboard is messy and not as well organized as it could be.

Love this app very easy to use Love this app very easy to use. I highly recommend for applications that require "fill in" sections, majority of us have terrible handwriting and there is nothing more annoying than explaining what you wrote. Also you want to ensure your application is submitted as quickly and efficiently as possible.
