The University of Leicester and Leicester’s hospitals have secured £2 million from the UK Space Agency, in collaboration with NHS England and the European Space Agency, to develop a mobile app addressing the challenge of managing long-term conditions for the NHS’ 70th birthday. The Personalised Space Technology Exercise Platform (P-STEP) app will leverage space data and artificial intelligence to provide disease-specific exercise advice at a 10-metre resolution, including pollution warnings. Led by Professor André Ng, the Leicester team aims to combine high-resolution air quality data with personalised exercise guidance, addressing concerns for patients with conditions like heart disease and asthma. The app aims to simplify exercise prescriptions, improve well-being, and mitigate the impact of air pollution on health. The demonstrator project is being delivered by a broad team including clinicians, computer scientists and informatitions, health psychologists, primary care providers and environmental health and Earth observation experts in collaboration with EarthSense, a local SME.
