I think this is the best scanner app

The UI could use a refresh but I like how the paper portion of my scans always look paper-white, and the text always looks sharp and black. Granted, the general workflow and the OCR and Dropbox implementation could be [really] better, but at the end of the day what matters most is the scan quality. You can manually adjust the corners by rescanning a document, and if OCR is really important for you, do like I do: scan to "Open In...", send it to the Dropbox app (thus circumventing DocScanners poor Dropbox implementation), upload it to a folder on your Dropbox and run the OCR in Acrobat on your Mac/PC. This has worked wonders for me. One more annoying thing: auto capitalization of document titles... In many languages, French being one of them, we dont capitalize every word in a title. It would be nice if there could be a setting to turn that off.
