A mobile travel app is a software application that has been developed specifically for use on smaller devices, such as smartphones and tablets, and can be used by business travellers to book and manage their travel whilst on the move.

Booking travel, altering bookings and checking itineraries are popular functions that feature on most mobile travel apps. Although useful to some business travellers, mobile apps can quickly become out of date and so more innovative travel management companies are remedying this by offering fully optimised mobile booking sites to travellers instead.
