One of my current favourite little apps is Genius Scan+ which I have on both my iPhone and iPad. Produced by @thegrizzlylabs this app allows me to scan documents as pdfs or JPGs, crop, add titles and tags to the document, merge several scans in to one document and then send by email or to Dropbox and the like. I like to use the iPad app for bigger scans but I think as the camera is not as good as in the iPhone the quality is not as good.
I think this is a smart little app and one that I find so useful for local and family history. Or just some little piece of correspondence that I need to copy. No more do I go to the flatbed scanner. And the quick interface with Dropbox is great for me.
There is also a Genius Fax app which I have loaded but haven't used as I haven't wanted to fax anything since I loaded it.
Does anyone else out there use these apps? And what do you think of them?
