Nanogold technology

How it works

Tiny gold particles in the tracker react when they sense hormones. In traditional OPKs, you see this reaction with your eyes. Modern trackers use your smartphone’s camera.

Mira • Registered and Patented Technology • scientifically considered

Fluorescent technology

How it works

The fluorescent label “lights up” when it detects hormones. This bright signal it produces makes it more sensitive and precise, making even tiny hormone changes visible.

Cameras are not optimized, not calibrated, and not validated to ensure consistent and precise measurements.

Instead of seeing a line, special equipment detects the fluorescent label. That makes readings much more precise, sensitive and reliable.
