Hi Drew, Thank you for taking the time to review the Ki Armband. We always appreciate feedback from our users and are constantly looking at ways to improve our service. It's great you noticed the accuracy of our product. The Ki Armband is most accurate calorie monitor current available with four sensors working together all the time to collect information about your body from over 5,000 data points. Although we do sell an additional display, applications for both iPhone and Android devices are available. All the best with your continuing #bodydata experiment. If you can measure it, you can change it! Sam and the Ki team.
