I'm almost positive this app works! I've used many other apps that supposedly say track ghosts, but this one seems to be the most accurate. I haven't gotten any hits or spikes on the radar at my house, (cuz my house obviously isn't haunted -.-) but I did get some hits when I went to the park with my 3 friends Daisy, Michelle, and Eilene. We got a lot of activity but got almost no evp's. Only one, when I was alone at the corner of the park while my friends were playing at the jungle jim. It started talking to me but couldn't make out what it was saying! Honestly, I was scared! I love this app :) and one of the many times I got a dot on the screen, my friend was holding my iPod then screamed, and through my iPod on the grass -.- it still works though xD out of all the ghost tracker apps there are out there, this has to be one of the best. Seriously, at least give it a try ;)
