T155 Mystery revealed

This tracker watch (Apple watch), like all things Apple, makes a huge contribution to my day.

Husband (technophobe) even has a Fitbit now. We often walk round the block ‘once
more’, or up and down our hallway, just to meet targets. He always succeeds, I do 5/7 days.

The three rings (which need to be completed
- and go from ‘tiny’ dots to full rings), are for:-

Pink = movement (pottering around)
Green= exercise (fairly brisk walking)
Blue = standing hourly (ie reminds you not to watch TV without getting up every hour)
