Too old and buggy

I got this mainly to join multiple PDFs into a single file. Unfortunately this crashes every single time rendering this an expensive and useless app. Would love a refund...

You don’t get the value out of this app.

I have been using this app over 6 months now and have had to deal with the same issues every day. App crashing, hiding my files, not working with Dropbox consistently, unwanted markups appearing out of nowhere. Buggy at best. Wish I hadn’t downloaded on three devices on a major podcast recommendation. That’s $60 I’ll never feel good about spending.

Counter-intuitive, very uneven quality

So I saved a pdf in the desktop PDFPen Pro, and sync’d it up to iPad (somewhat laboriously.... the iPad version saved two copies for some reason). I took it into the field and added some text notes, again laboriously. (You have to jab a the iPad version to get into your text box, and it keeps resizing itself.)

When I got back to he desktop, all versions were re
reporting that they were sync’d to the cloud but the desktop version had lost my edits. So had the iPad version. It was disastrous.

This thing need a lot more work and a lot more field testing.
