What do you like best?

The use of this app is so extremely simple and easy for the advanced tech person, all they way down to the not in the least tech savvy person. I have had all walks of life find this easy to use when we were not able to sign in person. It is also easy for me to set up signatures from my phone or my laptop, in no time at all. The ease of use for both sides, is what I like best.
