Although my favorite all around do everything PDF App is PDF Expert, I can certainly recognize Apps that are targeted at specific tasks and especially when they're FREE for a limited time. That's where Softsign comes in Softsign is designed to allow you to annotate and digitally sign PDF documents on your iPad, iPod touch and iPhone. It's a Universal App so it plays nicely with both the iPad and iPhone/iPod touch display sizes. You can import PDFs into the App using the Open In command from Mail, Evernote or Dropbox. My Evernote lovers will enjoy the benefit of an integrated Sync with Evernote. Once you have the PDF in Softsign you can draw right on top of it with the built-in tools or insert a signature field. This is great if your PDF is not an official PDF form as you can add Text where ever you need to. You can also highlight text in the PDF document. The signature placement tool is probably one of the best I've seen and I love that it allows you to scale the signature even after you've signed. Mine was a bit too small. Once you've finished editing/signing the PDF you can then save it back to any PDF compatible App as well as Email out to anyone you want. The App has built-in password protection to keep your sensitive documents/contracts secure.
My only minor (very minor) complaint is that while it's possible to undo or clear annotations, those commands are buried in another menu. I'd like to see them on screen at the same time that I'm doing edits so that they are one tap away. Otherwise, you can't beat this App for what it does and you certainly can't beat it while it's FREE. Don't wait! Grab it today here from the
Side note: At first I couldn't get Softsign to show up in the Open In command on my iPad. I tried it on my iPhone and it was fine so I knew the App worked. I even went as far as to delete it and reinstall it. Still nothing. Then it dawned upon me that perhaps there's a limit to the number of "Open In" apps that will show up in the list. So I tired deleting one of my other Apps that can handle PDFs and another one popped in the list that wasn't there before (not Softsign). I deleted another App and Softsign then Appeared in the list. Apparently the limit is 10 Apps for any one document type. This is an iOS limit and not the fault of Softsign.
