I have a call app on my iphone and use it all the time. I get tired of remote operated electric calls and just like when the tv remote doesn't work and you hold it above your head to see if that helps I can't stand wiggling around that much on a stand. I use a remote speaker with its own power source and a cable that plugs into my headphone jack. Kinda handy because my ballistic calculator is on the phone too. Damn these things but I figure if I own it I might as well make it work for me. I've had great luck and it has led many dogs, crows and all sorts of other critters right into my lap. Used in conjunction with a moving decoy it will certainly bring you luck. I'd much rather mess with the wire and not have the remote fail.
