I don't need legal documents very often & purchased to help a friend get through a difficult time. much better than hand writing all of the documents out. makes it look professional and I will probably use in the future as well, if needed.

It appears to be a good program and I intend to use it in my business and practice. One of the problems that I see is that there should be clearer explanations for some of the fields.

I have terrible handwriting and often end up having to tear up forms and fill them out again. Especially if the spaces provided to write information are small.
This program has worked perfectly for every single document that i have used it for. Very user friendly. Aligns text precisely.
Overall extremely satisfied with it.

An all in one PDF app for your files
One of the most complete and useful tool to work with your pdf files.
The amount of options to edit and do things with your PDF files is just amazing, for example in the editor feature you can add text, modify tables, add checkmarks, search and replace, edit text, makes notes and so on, and like this there are a lot of options for your file, like the possibility of add a personal sign, or insert and image, or make a password, this a really amazing app for your PDF fIles.
I really do not have any complain about this app, because it comes with all the tools that you need to work with your PDF files, even the free version as powerful as the pay one.

Highly will recommend to others. Easy to use, and I just enjoy the fact that I can edit the text box to where I want to put it and being able to change the size of the box. There are ,of course, more features, but this is feature by far has been the one I been using the most.

This program works great!
This program works great, sometimes things are a little off once you download and certain documents are easily editable while others can be a pain in the butt. Overall I like it & I think it's great. I would definitely use it & recommend it.
2022-05-09
I love that I can fill out forms and save them fax them from here and really anything I need to do in one area. I hate that it cost so much cause I’m on a fixed income and don’t have the money to keep it I can only use it for the free 39 days.
2021-02-27
I love the product just don't have the need to justify a full subscription. I enjoyed the trial period and had great Customer Service when needed. Very prompt with replies. I would recommend this product.
