You can connect your Misfit Shine or Shine 2 as a tracker device in KrowdFit.
Navigate to Settings > Fitness Trackers and select Add a tracker. Then sign in with your Misfit account to allow permissions. Once thing to note is device is a great steps tracker and will even record steps data while swimming. It will also report sleep activity. But it does not report activity minutes or meals. You will need to have another tracker connected to your account to capture those.
