What did Shark Tank company Breathometer’s original device measure?

Shark Tank company Breathometer’s original device measured blood alcohol level.

Breathometer developed portable breath-analysis technology intended to estimate alcohol concentration from a person’s breath. Its best-known early product connected with a smartphone and was marketed as a convenient alternative to larger breath-testing equipment.

Founder Charles Michael Yim presented Breathometer on Shark Tank. The company attracted a major investment from Mark Cuban and other investors, making it one of the program’s highly publicized technology pitches.

A breathalyzer estimates alcohol concentration; it does not directly measure blood itself. Results can vary with device quality, calibration, timing, and use. Breathometer’s consumer product should therefore not be treated as a replacement for law-enforcement testing or a safe-driving decision.
