See for yourself by reading reviews on the most popular resources:
This is an excellent program; however certain functions are difficult, especially "moving text" and aligning the text to create a uniform picture.

I find it tedious that I cannot page or scroll down with my cursor on the document. I also like pdf filler apps used by realtors that let you initial and then step to the next blank to complete.

I had an issue with a purchase for PDFfiller.com. I called customer service to get a refund, they were kind enough to honor my request. I would use them again.

Great app! Use it on my phone which is great and handy in situations where documents need to be signed and done in a hurry. Only down fall is mailing documents sometimes gets sent to spam or junk mail. So tell your recipient to check their spam box just incase.

Initially
Initially, it was a bit difficult to insert the text; but after a while I discovered the "T" tool for aligning texts. I also like the fact that I had choices for signatures.
