For weeks I struggle with the uneasy feeling that I'm not alone in my apartment. Again and again I wake up at night and hear sounds around me. My friends thought I was already partly crazy, but now I have the proof: Thanks to today's Amazon free app and the high-tech smart phone I could locate for people otherwise invisible activities and have razed to it, to scare the ghosts out of the window. This is best done when you light a little Wet Leaves from the outside in a small bowl. With the Ghost Radar I could follow the ghosts and eventually distribute. Thank you, now I can finally sleep properly. That's worth all 5 stars, especially this ingenious app is available for free today.
