Transport for London made life a lot easier for mums-to-be when it brought out its official "Baby on Board" badge, prompting Tube passengers to offer up their seats. However, commuters are often so engrossed in their smartphones that they don't notice when a pregnant woman boards the train. Now London-based innovation firm 10x has developed an app called Babee on Board, which should help pregnant women get other commuters' attention. http://www.mirror.co.uk/tech/babee-board-app-prompts-inconsiderate-9677387
