Garmin Cirqa Accuracy Deep-Dive Review (vs Whoop 5.0, Fitbit Air, Amazfit Helio, Polar Loop)
· By Endurance Wire
This will probably be my rabbit-hole post of 2026, diving into the accuracy of not just Garmin Cirqa, but all of the screenless wearable bands currently on the market. And not just one Cirqa band, but both wrist and bicep/arm placement, as well as multiple people. And finally, not just heart rate during workouts, but across a slate of different categories and scenarios, spanning weeks of data gathering/comparisons. As you might surmise, data accuracy is always important in a wearable, but frankly, even more important in a screenless band .
