What happens to the data on my Smart Activity Tracker if I pair it to a new smartphone?

If the Smart Activity Tracker AM 1800/1801 is paired to a new smartphone, the app starts to count from zero again. This is necessary in order to sort the collected data historically correct. We recommend to start the new pairing process shortly after midnight (as the tracker will be set back to zero then anyway) or in the morning, right after you get up - before you start collecting data for the new day.
