In grad school, much of my reading comes from pdf files my professors post. Prior to PDFfiller, I would print out hundreds of papers in order to annotate. Now, I can annotate while conserving resources and I have access to the files no matter where or what device I use.

I am taking online college courses and this has been a miracle for me to fill and physically sign forms, I have a touch screen computer so I can physically sign with my finger. Really love it.

I am happy with how to fill out the health claim form template. It is user-friendly and reliable. It is a little slow to open documents and I waste some time looking for the right one. I don't like the organization system and I haven't figured out Templates. I am not looking for a practice management system so I like buying only what I need. Overall, I like the app and I paid for a year subscription.
