(WTVR) Just in time for summer and all that standing water comes a smart phone app that repels mosquitoes.
It's been downloaded by millions.
The app claims to produce an ultrasonic high pitched sound -- undetectable to the human ear, but that scares mosquitoes.
Reviews of the app and others like it are mixed. There are several free versions, just search in the Apple store.
