HRG’s business technology and distribution director Bill Brindle and director of product development Paul Saggar have been developing the app, which will be launched at the Business Travel & Meetings Show at Earls Court today (8 February).
The first version of the app will include hotel booking features, flight and rail schedules and itinerary information.
Saggar said the drive for creating the app had come from clients, following a customer forum held in September, which focused on mobile technology.
"It is timely, valuable information," said Saggar. "With hotel booking, if you go to our hotel directory you will be presented with the same hotels as if you picked up the phone to one of our counsellors."
He added the capacity for flight booking was available, but had not been "turned on" for the app yet, because of the length of time the process would take clients on a mobile device.
Brindle said that as devices such as iPads and alternative tablets became more ubiquitous that would be the point at which clients used mobile for flight bookings.
The app also features the ability for individual travellers to visit their ongoing bookings offline, so they could check details of hotel addresses and flight times while on a flight, for example.
HRG chief executive David Radcliffe said: "I am really excited about it. This is our own technology, we haven’t bought a product in and I would far rather we were in the position of having the capability than not having it."
Other technologies HRG is showcasing at the Business Travel & Meetings Show include an extension of its i-Suite to allow travellers to make online reviews.
