Why do you want to know what people and dogs are doing in your absence? Spoils the break.
Of course the other way the development of an effective app impinges on everyone is that it would cast a lot of money. In the case of Cunard, an awful lot of money, because they would have to employ two sets of people, the second to correct all the messes made by the first lot. 😀 I should much prefer the money to be spent on other things, such as further improving food quality and choice, perhaps paying some staff a little more, having better value tours, employing quartets rather than trios, etc.
