WHO now also asks people to sit less, next to the 150-minute moderate target. Those are two jobs. An evening workout does not erase a day in a chair.

Reviews find short walking breaks during sitting, about every 15 to 20 minutes, improve post-meal glucose and insulin more than staying seated.

Opening the app every time you want a number makes the habit heavier. A step ring on the Home Screen is enough to decide whether to walk the hallway.

While you walk, Lock Screen numbers keep you from stopping only to unlock the phone.

The reminder is a tool. The benefit comes from real steps, not from the widget.
