Scentee, which is made by a Japanese company with the same name, plugs into your phone and releases a chosen scent when you get a notification, the New York Daily News reported.
That means that every time someone comments on your Facebook post or sends you an email, you could get a whiff of lavender or coconut or coffee.
The round, white gadget plugs into the headphone socket and contains an LED light that can be customized using the free Scentee app. You can also schedule the scent emission to match your alarm clock for a fragrant wakeup call.
The scent cartridges come in traditional fragrances like rose, jasmine and apple, as well as more unusual smells like curry and corn soup.
According to Scentee's website, each cartridge lasts for about 100 puffs.
A special "hana yakiniku" ("yakiniku" meaning grilled meat or barbecue and "hana" meaning nose) variety that releases the smells of short ribs, sizzling beef tongue and buttered potatoes, is set to be released on Nov. 15.
