If you're in the mood for food smells, Scentee has an app called Hana Yakiniku, which roughly translates to "nose grilled meat," programmed with three scents: short ribs, grilled beef and buttered potatoes.

In a promotional video, the message seems to be that the smell of meat and potatoes may be an appealing substitute for actual meat and potatoes.

The video shows a slender woman sniffing grilled beef as she chows down on plain lettuce, and a cash-strapped student happily deluded (through smell) into believing his white rice is topped with short ribs.

This marketing of imaginary meat is a bit strange, frankly. Clearly anyone who can afford this app, and an iPhone for that matter, is sufficiently nourished. And perhaps someone seriously in need of protein would not find it so amusing.

Tsubouchi insists the app is supposed to be fun, even silly. Look no further than the giant dismembered nose and promo copy describing the product as "revolutionary new deliciousness that mankind finally managed to develop after 7 million years of continuous evolution."

Still, we were curious — could the smell of meat actually satisfy cravings for it? Smell, of course, is very closely connected to taste. According to Marcia Pelchat, sensory psychologist at the Monell Chemical Senses Center, our tongues are able to distinguish between sweet, savory, bitter and tart. But "smell provides a lot of the variety in flavor," she tells us.

It's no surprise, then, that food manufactures have long been interested in using smell to manipulate our sense of taste. But to truly trick your mind into thinking you're eating beef, you would have to chomp on something that at least feels like meat. "I think you need the texture and the whole context," says Pelchat. Lettuce won't work, but fake meat might — which means this could be a good app for vegetarians with withdrawal cravings.

You'll be able to test it out for yourself in late November, when Scentee makes its U.S. debut. The Japanese will be able to purchase it a bit earlier — by mid-November. The device will retail at about $35, with the scent cartridges for $5 each.

Tsubouchi says his company is in talks with American food manufacturers, who are interested in developing advertisements that entice your nose as well as your eyes.

The company is also releasing a series of apps that link the scents to your phone's alarm clock, text messages and social media alerts. So you'll be able to wake up every morning and literally smell the roses (or the short ribs).
