As part of their first year of coverage, Channel 4 and Monterosa have launched Horse Tracker, a groundbreaking second screen app built on Monterosa's LViS technology with data from TurfTrax and audio watermarking from Civolution, the app allows people at home to track the position, speed and status of their horses as they race, in synch with the TV.

*Update* Check out the case study video:

The Grand National is Britain's biggest horse racing event of the year and over the course of the meeting, an estimated £500m ($760m) will be bet on horses at the Aintree meeting. It may be the nation's favourite race, but it's one of the busiest, most confusing and those who don't follow racing regularly often find it hard to see the position of their horse.

James Rutherford, Channel 4's multi-platform commissioner for sport said “In the heat of the live action it can often be difficult for viewers to track the position of their horses. Using real time data from the course combined with the latest audio-watermarking technology has allowed us to give viewers the chance to exactly track their horses alongside the television coverage.”

The app is now available on the App Store and as a web/mobile web version at channel4.com/horsetracker.

Horse Tracker is available for international licencing.
