But can it fill out a pdf file?

Basically I am looking for an app that I can use to fill out pdf forms, sign them and possibly make annotations on. One that I can purchase outright for a small dollar amount. I have no need for a monthly subscription. I would likely use the app maybe once a month or so. And Acrobat is ridiculous. So far I’m liking it.

Would not bother

Most annoying, this app keeps it’s own library of files instead of letting you save files you work on back to the same folder you pulled them from. You can export files in the paid version, but I would still consider that annoying. Just save the danged file! I already have an extensive folder/file system set up for my many chord sheets and don’t need it duplicated in the app. Just save the danged file! 2nd, the ad in the free version covers the bottom of the page. 3rd thing I didn’t personally like is that it only allows sideways swiping to the next page. To flow through a long chord sheet, I need continuous vertical scrolling, and I at least didn’t see that option in the limited settings. Although it did seem to be good at working with the Apple Pencil as advertised, doesn’t fit my needs overall and I deleted it after about 10 minutes of trial.

Don't bother, Complete waste of time!

I don't usually write reviews, but I was so annoyed with this app I couldn't let another human being deal with this crap. It won't let you add docs from mail (as it claims), only scanned documents are allowed. But wait, it gets worse.!?!? ! It doesn't even let you do that! I downloaded the scanning app, managed to upload a doc, but there was no way to then edit the app on PDF. The PDF app sent you to the scanning app, which doesn't return you to the PDF with the scanned document.

If their app actually does what it claims to, then it needs to be more clear. Don't bother, really not worth the effort.
