EthyloKey

EthyloKey is the companion app for your EthyloKey keychain.

TEST WITH EASE
Place your finger on EthyloKey for a few seconds. Your result appears as a simple color: green, orange, or red.

TRACK YOUR NIGHT
Add your drinks and meals to see how they evolve throughout the night. Based on the information you provide, the app estimates your curve, upcoming peak, and return to zero.

These estimates are theoretical. Everyone is different, and alcohol metabolism varies from person to person.

SHARE ETHYLOKEY
One EthyloKey can be shared with an entire group. Add your friends, assign each test to the right person, and compare your results in the Reflex Challenge.

You can also choose a designated driver for the night.

TEST YOUR REFLEXES
Measure your reaction time and compare it with your usual results to see how it changes over time.

UNDERSTAND YOUR HABITS
Find your tests, nights, and trends in one app to better understand your habits over time.

ETHYLOKEY+
Upgrade to EthyloKey+ for more advanced insights, including trends, summaries, and personalized features.

Without a subscription, EthyloKey's essential features remain available for free.

YOUR DATA, YOUR PRIVACY
Guest profiles and photos stay on your phone. Your EthyloKey account lets you access your own data when you switch devices and can be deleted directly from the app.
