I really like the fact that I can download PDF files, fill them in and save them on my computer. Once they are saved I can then print them or go in and change them.
2014-05-17
Great until I realized I couldn't use one form to save in different ways. I had to go back and delete and rewrite for each person I was filling the form out for.
2015-12-29
To start with I struggled a little bit and thought it wasn't working. However, five minutes into it I was already achieving what I wanted from the editing futures of this program. Many thanks.
2017-02-21
I was able to fill out a form easily and print it out. I had an issue and logged a ticket, and even though it was not an application issue, the support team was prompt and willing to help.

I like that I don not have to decide…
I like that I don not have to decide how big the text box needs to be, it does it automatically. I use it for work to fill out my time sheets or edit PDF files and it works like a charm.
2021-11-10
So easy and convenient to download and complete. My only issue is I wish with the forms you can scroll down to sections without having to tab each field or using you mouse to click in a different section.
2021-08-08
My only use is to help my 14 year-old grandson with his Eagle Scout Service Project report.
I'm retired and have no further use for the program beyond next year when he has completed his Project.
2021-02-12
Great, however, could be improved with quicker selection of initialing or signing. Maybe a way of clicking at the point of initialing and pasting without having to select each time you have to initial as slow if having to do lots of initialing.
2020-12-17
I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.
