Downloaded over 1 million times, Fart Sounds is the original and leading fart app worldwide. The name says it all. This is the real deal. No banners, no ads, no getting spam'd; just pure fart fun. It was even used on Conan O'Brien's show on TBS to create one of their segments. These 27 farts will make you laugh, cry, and hopefully embarrass a few people. Don’t accept any substitutes. This is a great tool; with everything from the interface to the sounds being made for the true fart prankster. Each sound was meticulously remastered to cut out any background noises and made to be crystal clear. Other apps will throw in a few sounds littered with ugly background noises that aren’t true to the clarity of a real fart. There is a “Help” page with easy to read instructions, as well as an email address for technical support and feedback. We promptly answer support requests and listen to any recommendations to help make this app even better!
