Great time-saver. I use this app a lot. It took awhile to figure it out and you need to make some effort to get your signature setup. Maybe there was a better way, I scanned my signature - put it into Photoshop and made the background transparent. Luckily I had those skills. Then I loaded it into PDF Signer and found it easy and quick to use. Transparency is very handy, because it can go anywhere in the document and overlap lines. Again, maybe there is an easier way to do it than I used. I rate this app really highly because of all the time and effort it saves me. Load the doc, add my signature, and even type in additional info (like the date) as needed. Love it!
