The Tech Tracking Lost Dogs

In Click, the team speaks to Olympian and tech founder Jess Ennis-Hill about her period-tracking app, which gives women exercises based on their menstrual cycle. The show goes behind the scenes of CrossRail in the UK, before the Elizabeth Line opens to the public in London, to discover the tech keeping it on the rails, and the team heads to Norway to test out some software that could allow lost dogs to be found via crowdsourcing.
