Click talks to Olympian and tech founder Jess Ennis-Hill about her period tracking app, which gives women exercises based on their menstrual cycle. We also go behind the scenes of Crossrail, before the Elizabeth Line opens to the public, to discover the tech keeping it on the tracks, and we go to Norway to test out some software which could allow lost dogs to be found via crowdsourcing.

Click investigates the new therapies being developed to help with brain repair. We also explore the future of air travel and catch up with astronaut Samantha Cristoforetti about her mission to the International Space Station.
