I'm learning it slowly. You cannot merge files in the app on ios. I need that. There are also a few hic-ups. Sometimes after a signature the screen gets disoriented and you have to go back to documents list and reopen. Sometimes after reopening some of the modifications are gone and you must re-enter. Some of these issues may be due to not being connected to internet. Overall it has helped me go paperless and I'm getting faster at filling out my documents using it. A few tweeks and it will be awesome.

I mainly use it to edit papers for my teaching position; it's been very useful to not alter the original format while adding my view point freely on the document.

I have found it useful to complete a myriad of forms required for our charity administration electronically - rather than having to print, complete, scan etc.

if the connection of the internet service provider is weak the form you type is loading until the connection comeback and repeat again in where you are last typing.
