The Problem: The Signos App (which tracks blood glucose) requires calibration to your body in order to give accurate recommendations. This requires that new users perform moderately involved exercise test. Taking this test with a mobile phone in your hand, while possible, was a less than ideal experience. The Solution: We realized that all of the timing cues as well as the members inputs needed could be conveniently performed on a well designed Apple Watch app. This would make this test easier and less risky for those trying to multi-task while exercising. The Result: The launch of our Apple Watch made this function much easier and more delightful for our members. They were able to perform the exercise test as well as measure their personal glucose changes in a much more convenient and safer way.
