Frequently Asked Questions

SENSOR & READER

How long does one sensor last? ▼

Each sensor lasts 15 calendar days from the moment it is first opened. The biochemical layer begins degrading when exposed to air, regardless of how much you use it.

Is Cori designed only for workouts, or can I wear it 24×7? ▼

Cori is designed for 24×7 wear over the full 15-day sensor lifetime. Most users wear it before, during, and after workouts for recovery tracking.

Is the Cori sensor completely needle-free? ▼

Yes. Cori is 100% needle-free. It relies on passive diffusion from interstitial fluid and sweat. No skin penetration.

Can I swim or shower with the device? ▼

No. The biochemical element can be damaged by submersion.

  • No showering
  • No swimming
  • Rain and sweat are fine, but do not expose the sensor to running water or immersion.
What is the device's battery life? ▼

Up to 7 days on the default sampling rate (30 seconds). Higher sampling frequencies reduce battery life. A full charge takes ~2 hours.

APP, DATA & CONNECTIVITY

Can I export my data? ▼

Yes, Cori exports to FIT and CSV formats.

Can Cori stream data to head units, Garmin, Apple Health? ▼

Yes. Cori will provide an API that supports:
