And it promises to 'annoy everyone in sight'.
Heard of Vuvuzela horns? They're popular in Africa for sporting events: when blown, they make a sound akin to a swarm of angry bees.
You'll know them well by the end of next month's World Cup, trust us.
Anyway, UK firm MD Media Consulting has launched a free iPhone app that captures their unmistakable sound. It could be this summer's iPint / iFart viral hit on the App Store.
"Annoy everyone in sight, in the pub, wherever.. whilst watching your favourite football team etc getting thrashed," promises its App Store description.
A branded England version is on the way, as is - strangely - a version for the Lacross World Cup, which is due to be held in Manchester this July.
