Frequently Asked Questions

Q. Steps are not added to the Step Challenge (even when the steps in the lifelog increase, they are not added to the challenge).

The step count displayed in the Lifelog is linked to Apple Health/Google Fit, and the app or device function may automatically adjust and deduct the steps that are counted too many. On the other hand, the steps in the Step Challenge, once added, will not decrease. Even if the steps in Apple Health/Google Fit decrease, the steps in the Step Challenge will remain the same and will be counted again once your actual step count exceeds that number.
