Great pdf editing app

I use Smile pdf software on my iPad and my Macs. I also use the related pdfPen Scan+ software when I need to convert pdf text for word processing. The app is not a substitute for the pdfPen 4.

The power of this app grows with each new release. In addition to text correction, the app now supports forms, document signing, watermarks and TextExpander

It doesn’t recognize forms... Worthless!

Honestly, the hype is just that, hype. Five minutes with this app and I had to get a refund. This app does not recognize forms. There is no way to fill fields on forms and move from one field to the next using your keyboard. You have to tap into a space using your finger or Apple Pencil. Then there is no way to move on to the next field using your keyboard. You cant use tab, arrow keys, enter, anything. There are little arrow keys in the lower left of the screen to move from field to field, are you kidding me? If there is a field that only accepts numbers in the document, PDF Pen will not allow you to enter the cursor into that field- The arrows will skip you way down the page to some random field. If your form has calculations built in you can be sure PDF pen won’t recognize that either, your columns won’t tally fella. Don’t count on your form looking neat when you’re finished, this app cant find the the bottom of the field to rest you text on the line. Useless.

This means there is still only one PDF editor out there that actually works to fill forms and that’s Adobe Acrobat at $9.99 a month! No thank you! Is there anyone out there that can make a decent PDF form app other that Adobe? PDF Pen isn’t it... Be assured of that.

Oh and developers, I see your responses to other customers...all automated responses. Don’t bother if you’re going to be lazy about it.

So close…

PDFpen has been my go-to on the Mac for years. I wanted to like this app on the iPad, but it’s just not quite there. The two items killing it for me are:

- There does not seem to be a way to scroll between pages while the annotation tool is active. If you use the sidebar to switch pages, the annotation tool is deactivated. I’d like to be able to scroll through a 10-page paper and make comments without having to resell them a tool every page. I also need to be able to switch quickly between pages as I reference items in previous areas.
- The Pencil “smoothing” algorithm isn’t up to snuff. MS
Word, iOS’s native markup, and PDFexpert all have this smoothing down pat. PDFpen stutters, overcorrects, and occasionally sends a streak halfway across the page when I’m trying to write a comment. Please talk to the Apple engineers to figure out how to clean up this algorithm. I’d love to move to an all-PDFpen workflow across my devices!
