I really like the app called Pear - which when you go our of range of bluetooth it buzzes and sayd "Have you forgot something?" and then can ring your phone so you can find it. When I'm using satnav in the car the directions come up on it. It's in black and white, but when I raise my arm it changes to colour. I've just discover I can say "Ok google show me picture of Porsche 911's" or whatever I want and scroll through them... people love that. Hoping you guys will have a whole load more tricks
