App Rewards Frequent Fliers For Matching Every Mile Flown With A Calorie Burned

App users are challenged to "match every mile they fly with a calorie burned in the space of 24 hours after they land." For example, if you flew about 1074.52 miles from Latvia to London, your target would be to burn that same amount in calories.

Calories burned are tracked using a built-in accelerometer that is found in a smartphone.

Should a passenger successfully burn a calorie for each mile flown within the 24 hour period, they will be rewarded with more points and therefore stand a greater chance of winning more prizes.

The aim of the project as a whole is to offer encouragement to frequent fliers to find the time to exercise and keep fit, despite their hectic schedules and long hours spent on planes.
