I have really enjoyed using the software. I use it on my iPhone, on my windows PC, on my Mac and my iPad so it's a multiplatform Holy Grail. I still use the program. Have it installed on all my computers and IOS devices. there are a lot of features that I've not used so I can't truly say much about them, but overall I'd definitely recommend the program to others.
2020-08-24
I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.
