The official Bing Health and Fitness app is adding pedometer functionality, starting with the Lumia 630 and Lumia 635 when they launch shortly. This is leveraging the SensorCore SDK that was made available to developers last month which allows motion tracking without taking a big bite into device battery life.
As you might expect, the Bing Health and Fitness app helps its users stay in shape by counting calories burned, tracking what they're eating, and providing a full workout regimen. A pedometer is a no-brainer addition to an app like this; keeping tabs on footsteps will provide a more precise reading for frequent runners.
With any luck we'll see the feature roll out to other Windows Phones like the Lumia 1520 and Lumia 930 once they get their Cyan firmware updates. Phones with the newer Snapdragon 80x chipsets can leverage the SensorCore technology, so older Lumias won't be able to partake.
