I tested my Fitbit Air against an 'EKG-accurate' heart rate monitor - the results surprised me

Accuracy is the name of the health tracker game, so I put Google's latest device to the test.

Why this matters
Why now

The continuous release of new health tracking devices like Fitbit Air leads to ongoing comparative reviews to assess their real-world performance.

Why it’s important

This article offers a direct comparison of a popular consumer health device against a more clinically precise one, informing consumer choices and highlighting product accuracy trends.

What changes

Little fundamentally changes, though it provides specific data on the accuracy of a particular consumer wearable heart rate monitor.

Winners
  • · Consumers seeking reliable health monitoring devices
Losers
  • · Companies whose health trackers perform poorly in independent accuracy tests
Second-order effects
Direct

This test result may slightly influence consumer purchasing decisions for heart rate monitors.

Second

It reinforces the broader market perception of accuracy differences between consumer wearables and medical-grade devices.

Third

Long-term, consistent discrepancies could push manufacturers to invest more heavily in sensor accuracy, potentially leading to regulatory scrutiny on health claims.
