iPhone users now have another weapon at their disposal when shopping. No, not that blood-stained crowbar–save that for Black Friday. This one is called Flow, and its the newest application from Amazon subsidiary A9. Flow uses both barcode and image recognition to continuously recognize millions of products in a live camera view; something even your grandma can’t do, despite her meticulous scanning of the Sunday newspaper coupons and The Price Is Right watching. Just point your iPhone at the package and instantly you get info on pricing, availability, reviews, and more. You’ll be able to decide on the spot, “Hmm. Do I by this combination toaster/bath gel dispenser now, or snag it online?” These, my friend, these are the questions you will now be able to answer. Oh, and its free.
