Technology designed to keep us safe can often come about as a result of a tragedy.
In this week's Swipe, reporter Kit Bradshaw meets a teenager who's developed a fire safety app following the devastating Grenfell Tower fire in London.
Meanwhile, Swipe presenter Gemma Evans investigates the growing and tingly phenomenon of ASMR and even gets a look inside the 'Tingle Shed' where social media star Emma 'WhispersRed ASMR' films her hit videos.
Plus, games reviewer Simon Miller brings you his pick of the latest releases including EA Sports UFC 3, Dissidia Final Fantasy NT and Railway Empire.
