Graphic arrows in the pdf are represented by the letter U. Can't move inserted text to new location. Circle is useless, odd shape, can't resize without border getting too thick and covering item to circle.

Easy to use -- several format/file extension options for saving and ability to link with cloud and sharing platforms makes this so versatile. Having the option to save a filled form as a template is very helpful. The customization and array of options is allowing me to complete tasks, for which I previously needed multiple programs.

Useful form creation and library tools
Makes confirming client changes and work ideas more fluid with notifications of form signing. Wide tool set and excellent selection of preexisting forms.
So many forms and flexibility to edit and create and cross share forms with clients, and the addition of the iOS app makes for a great always on solution and current information.
Price is ok, for single users but for larger firms it may be a consideration. So far no other issues

This is the best PDF program Ive used
This is the best PDF program Ive used. Ive long wanted something to compete with Adobe and this is it. I love the ease of using all features, especially the editing/adding text option. This program is top tier! As a healthcare provider who has to often complete forms for patients, this program exceeds my expectations.

Our previous subscription was deactivated because no one seem to know the login or password for the account. It was assumed a temp employee had subscribed who is no longer employed. Difficulty accessing and filling online forms prompted us to re-subscribe. This morning's experience has been great and we plan to continue using this application.

It was easy to navigate tools.
It was easy to navigate tools.
But I would suggest some additional edits for the photos such as free clockwise rotation when necessary

They have great customer service
They have great customer service. I got charged my yearly fee, which was a mistake, and when I notified them they quickly took action and reimbursed my money. Thank you. The items provided by you are great, but I do not use them all year.

It's great. Noticed some glitches on the forms, e.g. the text-in-th middle selection populates horizontally instead of vertically, making it impossible to see all that has been typed without scrolling across.
