It tries to force you to make an account, but you can actually use it without logging in. Just open your file directly from your file manager. After that, it was easy to use, and I was able to save my signed PDF. Hopefully the devs won't "fix" that workaround after they see my review. 😝

I like this app a lot, but I'm constantly running into different problems. One of the most frequent errors seems to be a login error. It is so incredibly frustrating. I am giving up and trying something else, as this app is rather useless without logging in.

no option to download my PDF locally after editing. all support topics point to a "download" menu option that literally does not exist on my app. I understand this is a cloud based service, but people edit PDFs for things like taxes and applications and thus need to have permission to obtain a local file. this is pretty bummy user experience tbh. update: eventually found it but had to dig. this should be an easy to access feature
