Clinically proven to be accurate
The Ki Fit System has been clinically proven to measure calorie burn and levels of physical activity accurately. It is a medical device and as such, features some of the most cutting edge technology on the market.
A recent independent study tested the armband in real-life situations. Participants engaged in a broad spectrum of pursuits from brisk walking, running, cycling, ball games and strength training through to sedentary, home and work-based activities.
The study compared the armband to a '£25,000 portable oxygen analyser ' recognised as the 'gold standard' for assessing calories. The results showed a mean error of less than 10% in measuring total calories for free living activities, and less than 5% in total minutes of exercise.
