Why the right size matters
Smart ring ≠ jewelry ring
A smart ring needs continuous skin contact for accurate measurements.
Fingers fluctuate
Your finger size changes throughout the day. That’s why you test for 24 hours.
Fit is everything
Too loose = inaccurate data. Too tight = uncomfortable.
That’s why we recommend the SizeKit if you’re unsure.
