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

Once upon a time, this app was at least close to best of breed. Unfortunately, this app has not held up well with the advances that have come to the iPad. It’s support for the Apple Pencil, for example, is especially disappointing. You can’t double tap to erase, and even the pencil tracking is slow and imprecise, which produces a rather frustrating experience when writing.

You’ll want to look at GoodNotes or MarginNote 3 (or better), the latter of which (presently?) even offers a 14 day free trial.

Outstanding App & Developer

I’ve purchased every version of PDFPenPro for Mac OS and the iOS versions since they first launched their first app. The developer consistently updates the app. Their customer service is excellent. I highly recommend all products from this developer, including TextExpander for iOS and Mac OS.
