Ok, so, me and friends, we went to my dads house, and you would NOT believe how old it is (sowwie Dad!) Its like a haunted mansion!! So anyways, we turned of all the lights, and we left the TV on, to see if the electrical current had something to do with this app. I went near the plug with the app, and nothing happened. My friends did the same thing, and still nothing. So we went upstairs, but half-way up the stairs, me and my friends meters started spiking at this huge hole in the wall. Then almost 5-6 minutes apart of leaving this app near the hole, we had all caught ONE ghost. Maybe its a vortex. You never know. We continued on our journey, found 3 ghosts on my phone, 4 ghosts on my other friends (Cassies) iPod, and 2 on (Aaliyahs) phone. Then we started hearing knocking sounds, not the app, but REAL knocking sounds, and the floor were wood, and we got scared. I told my dad we were going to spend the night at Cassies house, but i never felt right about my fathers house. Me and my friends are going to do further investigation next week. Happy ghost hunting!
