I guess it was a quiet day although it needs be said Actifit stopped tracking despite aggressive mode activated.
Yet, I think I have noticed some interesting things about the tracker. Yet need to observe more.
Basically it boils down to Actifit Android not filtering anything tracked via the sensors.
MI Fit (via band) and iOS are close to each other. When syncing to Google Fit via MI Band Notify app (manually activated in pro version), Google Fit comes close to Actifit score. Yet, Notify app itself doesn't count those "shakes" as steps itself.
More observation required.
