If your copilot hasn't received any energy from you in a while, there are two possibilities:
1. It may be that you recently haven't been walking much and therefore haven't had enough energy to transfer to your copilot. (At least 100 units of energy must be produced to begin energy transfer.) The "last online" time would reflect the last time you had enough energy to transfer.
2. If you actually have been walking a lot, Walkr may not be accurately recording your steps. In this case we advise you to consider the below articles regarding problems with the pedometer:
