Planning a trip, whether it is for business or pleasure, can be a fraught task. KAYAK enables you to take control of the entire process from the comfort of your iPhone or iPad.

The app can be used to search for and book flights, rental cars and hotels, and advanced search filters can be used to ensure that you home in on only what is most suitable. Bookings can be placed directly through the app, or you can click a link to be put through to an operator if you need to make any queries. When en route, the app can then be used to keep an eye on slight status as well as managing your trip itinerary.

You are not obliged to book through the app if you do not want to, you can use it for purely informational purposes. You can check the price and availability of seat on flights with a number of different airlines and book elsewhere if you desire.

There is also a cut-down version for your Apple Watch, which will enable you to monitor your travel plans from your wrist, get quick alerts for flight changes, your flight gate and enables you to toggle between current and planned trips.
