allows you to add text. you can change font size but the text color is blue and you can't change it. allows you to add signature but it's not very sensitive. Will come out sorta looking like your signature but just a little rounded off. but overall it does the job and will allow you to fill and sign any pdf document

Seems it has one task and that one has limited ability to allow decent flow and fluidity signing with a stylus. The signature is missing humps, bumps, and curves associated with my signature dispite 100 trys. Haven't figured out how to actually bring ia document to be signed from within the app...but share to from another app allows a signature. Not anything i can't do physically for free. I might consider purchase of i had a better idea of what that would add to a simple app. TRUTH: keep 🔗

Hi Wes, thanks for reviewing. Not sure we understood everything you wrote, but to clarify: with the Free OP.Sign plan you can sign, send to sign, share into and from OP.Sign and much more. OP.Sign Premium offers you even more security and flexibility. Please mail to contact@op.today and we'll review the signature drawing process together, thanks

It is hard to add text to a document because its difficult to move and adjust the size of the text, you need a lot of patience especially if it's a large document. But when you download it to a pdf then open and check it's right all of your added texts will be different sized and not match the work you did. Overall it's frustrating and a horrible experience. Save yourself the time and pain I have already spent trying to use this app.
