I'm still on the learning curve. Would like to have a way to erase large sections of a page, not just strips of it. If there is such a way, I haven't yet discovered that.

I have used a couple of the other apps and I believe that the PDFfiller is the easiest with very self explained instructions. I love the fact that the mobile app is just as user friendly as the app on my computer. Thanks

The signateure date and initialling has to clicked for each time. Would like to be able to just click the option and repeat that option several times without selecting it.
What problems are you solving with the product? What benefits have you realized?
Can send out contracts and paperwork. Re-formatted the paperwork to be filled out electronically and it's much clearer.

Using the app has been pretty easy so far
Using the app has been pretty straight forward and intuitive. Getting used to how to edit a PDF to get consistent results. Has been a big help. Users always want a free solution and I'm still testing the 30 day trial but maybe if you want the right solution it needs to be a paid solution.
