### 1/5 — Doesn’t Work

*2022-03-05, version 2.1.4*

Great idea, but the mobile browser button to sign up for the account I wanted didn’t work no matter how many times I pressed sign up.

It worked in the app to sign up, but when testing the app under the demo document the moving of the text box on the signature and date line was dysfunctional, often times only allowing me to make the text or sign box bigger or smaller but not allowing me to move it in order to center on the line.

### 5/5 — Amazing 👍

### 5/5 — Great app.  But how?

*2021-01-29, version 1.4.3*

I have to admit, the UI is great. And integration with Monday.com is what led me here. I have one large concern before rolling out however, how is this app free? Where do the developers actually get compensated?
