Both go to bed 30 mins earlier so she gets the same amount of sleep? Or alternatively, suggest that you start going for a jog/whatever together in the mornings so she has an incentive to wake up the same time as you. Sorry that it's not the most high-tech of solutions. I could probably make an app for monitoring both of those if it helps :-S
