Maybe fake! – Ghost Detector - Haunted Radar Review

So I got in the app and it said there was a ghost,I got out of the app and got back in and it said the ghost was gone.?But I have another story,So my older brother would always hear footsteps in his bedroom and he would get a warm chill at nighttime.So we got the app and it said it detected a ghost!?So it could be fake or not.Thank you for listening!?
