How we stack up
Why AURORA.
Not the others.
We built AURORA because the smart ring market had an obvious gap: premium hardware that didn't come with a monthly subscription extracting recurring revenue from your biometrics.

LED display
AURORA includes a built-in LED display — glanceable data without reaching for your phone. Neither Oura Ring nor WHOOP have this.
