Is Your Smartphone or Smartwatch a Good Enough Fitness Tracker?
Consumer Reports has no relationship with any advertisers on this website.
Many smartphones now come with a built-in step counter. And smartwatches often track steps plus your heart rate. So why bother investing in a stand-alone fitness tracker?
Consumer Reports tested step counting on an iPhone 7 and a Samsung Galaxy 8. The phones were carried in a front pants pocket, a shoulder bag, and a runner’s armband.
When each phone’s scores were averaged, we found that both counted steps about as accurately as an excellent stand-alone fitness tracker.
