When I first saw this South Korean 'virtual girlfriend' app, I thought it was an incredibly sad thing to buy, but on reflection if it helps combat loneliness, then perhaps that's no bad thing. For £1.26 a day, the app will send you four video calls a day (out of a possible 100) from a model posing as your girlfriend, ranging from "Are you still sleeping? Time for breakfast!" to "Good night, sweet dreams". Just one thing, as Geekologie pointed out: remember to delete the app if you get a real girlfriend.
