If you have trouble waking up in the morning check out the latest social innovation for your smartphone; Wakie. This free app for iOS, Android and Windows Phone 8 lets you sign up to have complete strangers telephone you to get you out of bed in the morning. You can also sign up to be the alarm-caller (if you have a sadistic streak in you?). The service is completely anonymous and no personal details are exchanged, so you don’t need to worry about getting prank calls when you’re not expecting them. That doesn’t mean the experience will be any less weird… that really depends on who you get calling you, which is a lucky dip to some extent. Upon signing up you are asked for your age and gender and the app will try and pair you up with someone a similar age and of the opposite gender. I’m not sure why they make the gender distinction, as it seems to corral users into a kind of heterosexual exchange that is very odd for first thing in the morning. Not that it is meant or marketed as a dating app… but it’s a shame you can’t make that choice for yourself rather than having it forced upon you.
