Remember the “Eq-Tool,” the gadget that was crowdfunded last November to help improve your equalization skills?

Well, the gadget’s Italian-based developers, Uba Project, met their €18,000/US$20,514 goal and recently announced that the accompanying EarON app is now available on the iTunes app store. (An Android version is “coming soon.”)

The Eq-Tool gently blows air into a nostril, opening the eustachean tube and making the eardrum vibrate. The amount of air pressure you apply can be increased or decreased depending on need and is measured by a wireless sensor connected to a smartphone or tablet.

The part that fits onto the nostril is hypoallergenic, washable and is available in three sizes: 20mm, 22mm and 25mm (.79 inches, .87 inches and .98 inches). It retails for €136/$155 “vat included + shipping,” according to the Uba Project website.
