It displays a color code: green when you're clear to drive, orange when alcohol is detected but you're still within the legal limit, and red when it's unsafe to drive. The reading is based on a multi-sensor array and machine-learning algorithms that analyze ethanol through your skin.

Under 20 seconds after your finger touches the sensor — fast, discreet, and reliable.

Up to 100 tests on a single charge. After 30 minutes of inactivity it enters sleep mode to save power, so it holds its charge for several weeks.

Place it on any Qi-certified wireless charger. A full charge takes about 45–60 minutes.

It's splash-resistant but not waterproof. Avoid full immersion or prolonged exposure to high humidity.

Yes — over Bluetooth, for history tracking and smart reminders. The device also works on its own.

No — and we're upfront about this. EthyloKey gives you an indicative reading (green / orange / red) to help you make a safer decision before driving. It is not a legally certified test. Only devices administered or certified by authorities (police breathalyzers, forensic labs) are legally admissible. You remain responsible for complying with your local laws.

EthyloKey is a new electronic prevention technology designed to help you make safer decisions before driving. Its readings are indicative only and not legally certified. For legal or forensic purposes, only tests administered or certified by authorized bodies (police breathalyzers, forensic labs, certified evidential devices) are admissible. You remain fully responsible for your actions and must comply with local laws. If you need a legally binding result, use a certified test or follow instructions from authorities. Ethylowheel is not liable for legal consequences resulting from reliance on its indicative readings.

It's designed to meet EU safety and consumer standards under the General Product Safety Regulation (GPSR) and for CE compliance. Note that this covers product safety — it does not make EthyloKey a legally certified alcohol test (see the question above about legal use).
