Hotel Tonight is a well-reviewed smartphone app that specialized in last-minute hotel bookings. Currently, there are promo codes active that can get you free credit good for any hotel available on the app. The selection is pretty good in my brief experience. Found via xlilsp1keyx of FW.

The apps automatically detect page corners and “flatten” the raw images into a high-quality scan with results that are very similar to a traditional scanner. From there, I can either e-mail the file or upload it to Dropbox, Evernote, Google Drive, etc. I find myself using it very often for both business and personal reasons.
I totally missed this app the first time around, but PaperKarma is an iPhone/iPad app and Android app that helps you stop junk mail. Catalogs, magazines, coupon books, flier, credit card offers, yellow books, etc.
