The word stairs, twice over
“I have tried this against top ghost hunting equipment and that cost a lot of money.. We are paranormal investigators and have our own YouTube channel on one of our vids in a wood you clearly see the app spell stairs when asked if the person had lived there.. A few seconds later the £160.00 SB11 device shouts out " No Down Stairs" backing up what the app spelled this app I see is going to go a long way and no one mentioned and words before hand for the bank to copy.”
