Neighbourhood Watch app concept - Perhaps signs in the community could display a scannable QR code which allows residents to communicate and come together as a neighbourhood. Activities, fund raisers, planned works, general information, crime reduction and general messages could be shared to bring a community together. Possibly a virtual group could help to physically bring a community closer.
Waste not want not A-2-C - How many times do we see large lorries on the motorway completely empty. Could there be a way to use this wasted space via a website or app. For instance if lorry was driving from London to Edinburgh with a full load. Could there be a way to connect them with someone on route who could fill that space?
Domestic Violence safety app - Could the police provide victims under protection an app which could make sure they are kept well away from those who would do them harm. Smart phones ring fence technology could be used. The police could use this app in conjunction with electronic tags. Victims could also communicate with police via messages and also alert them if any problems arise.
