I am not a great computer application user but I found PDFfiller easy to use and figure out. I even was able to place an electronic signature on a document with a little trial and error. Very nice application that I will use more and more.

filling our immigration docs that were not savable and this app totally helped me to save them and get back to the docs when I have more info. Awesome. One recommendation: I would like to be able to save to a specific file in my computer rather than have to move from the download file :-)

I have trouble using the pdffiller on my laptop, I can not upload b/c the screen is not wide enough to get to the click button. I can on my desktop when I go into the office. Sometimes the app does not give me the ability to save or download - I have to play with it back in forth before it will save as a fillable file. But my biggest issue is using my laptop when I work remotely and I have to use it. Thanks for inquiry and the survey to give me the opportunity to voice a concern.

great for data control I've only started using the program and so far it is doing what I want - merging my weekly quizzes together so I can show parents (when it comes time) all of their abilities rather than just the top 3
