I downloaded SignNow to test its core functionality, and I was impressed with how easy it was to upload a PDF and add my signature using the "draw" option. The interface is clean and intuitive, making the whole process from import to signing very fast. I also liked the ability to quickly create a reusable template for documents I frequently fill out. This app is a reliable solution for managing paperwork on the go.

Unable to edit text fields. I have a template set up where all I have to do is edit a couple of text fields and then create a new document copy, but this app doesn't allow me to edit text fields. The experience on a mobile browser isn't functional, either. So I'm stuck needing a laptop to make changes to the template before I can send it to a new client to sign.

Aston hi and sorry if any confusion! signNow is a e-signature solution, not a document editor, correct. If you need text edits in the existing doc, we can actually recommend couple partner solutions present here on Play. Please take a look at pdfFiller and/or DocHub, both are PDF/document editors and can do what you need. Hope this helps!

I have been using the SignNow app for a few days, and it has made document management and e-signing extremely easy. The interface is clean, uploading files and applying signatures is smooth, and it saves a lot of time. Highly recommended for remote work and digital paperwork!
