WorldMate
The closest thing most of us will ever have to a personal assistant, albeit a lot cheaper. All you have to do is forward your various confirmation emails for flights/hotels/hire cars/restaurant bookings to trips@worldmate.com and the app instantly generates an itemised itinerary covering your entire trip. Better still, upgrade to the premium version and the app will keep you in the loop in real time, generating alerts to let you know when flights are delayed or gates change.
Available on iPhone (free) and Android (free).
