Big fan of GS+. Scanning ppwk -> Dropbox and it's immediately on my laptop, super easy. Multi-page PDFs are awesome, just used it yesterday to send in some banking paperwork.
I used to use Genius Scan, but switched to Scanner Pro. It looks like genius scan is adding some of the advantages that Scanner Pro has though; like hands-free scanning.
@chhhris Scannable is great, but think of Genius Scan as your standalone scanner. We can export to Evernote and lots of other places. Scannable is more designed to work with Evernote only.
Recently I was looking to get serious about digitalizing my life. Scanning receipts, Passport and everything, I tested this app and I must say it's completely amazing.
