It works but with some very annoying problems
This app seems to fill PDF forms at first but there are problems:
1. The input text is too big. When I add 9-point text to the form, it shows up a few points larger. If I open the same file in Preview, its the correct size but offset to the left and up. So its actually quite tricky getting text into the correct location on the form.
2. The check marks are huge by default. The app doesnt remember my preferred check mark size, so I have to resize each check mark. This is quite tedious.
3. If I save the file and close it and then reopen it in this app, none of what I previously added is editable any more. This is the worst of the three problems because it means I have to get it right the first time.
