My first day! As far away from tech savvy as you can get! With help on "Team Viewer" I learned how to solve all the problems I had getting started. I will certainly use tech support again but off to a fun start.

It was pretty easy to use except when you hit the next tab it would take me to the text box to type but it would not allow me to type until I moved my mouse to that location and click. It would be easier if it would allow you to type in the box it moved you to so you don't have to keep going back and forth to the mouse. Also some boxes when completed there was not an option to click "next.

I subscribed for one purpose - to be able to print numerous amounts of Genealogy Forms. This is fulfilling my needs with minimum issues. It is a great product.

My wife had some US Government forms that needed to be filled out and returned. Because of her medical condition, she couldn't fill them out longhand, and she asked me if there was a way she could type and fill them in. We couldn't find access to a typewriter (WHAT'S THAT???), but I searched on Google and found information about your app. I had worked with some PC-based forms applications before, so I knew what type of function I was looking for. I scanned the forms into a PDF, and PDFfiller opened the files and allowed me to create editable fields on the forms which she then filled using your browser-based app. It got the job done! There were a couple times where she thought she had lost everything, but because of the automatic save function, nothing was lost. Unfortunately, I don't have any other immediate need for this, but I certainly hope you use this for promoting your product. I would have given it 5 stars had there been an apparent way of copying all the fields I added to one page and paste them onto identical subsequent pages in my document (you know the Government--lots of duplicate type information!). I had to create the same fields over about 8 or 9 identical pages on one of the forms. If I find I do have more use for this app in the near future, I will purchase it!

PDF filler works great and has helped print some documents that we used to have to type. Less time spent on creating forms for the clinic. Document creation - used it for paper billing, in house forms, and staff checklists. Easy to create the document and implement Alignment is sometimes different on the document than what prints. Can take a little trial and error to make it align perfectly.

I was very happy with pdfFiller I was very happy with pdfFiller. There is a variety of fillable forms. This would have been great if it had been available when I was active in my business. It is great for the occasional form that I need.
