NHS Go is a mobile app designed by and for young people to help them navigate health services in London. Focus groups of over 500 young people provided input on what topics and features to include. The app provides health information, helps users locate nearby services through their postcode or location, and outlines their rights. An initial marketing campaign using social media influencers helped the app reach over 33,000 downloads. Next steps involve expanding content, refining the service finder, gathering user feedback, and continuing marketing through social media.
