How to use Floome?

Floome is very easy to use:

  1. Launch the Floome application on your smartphone
  2. Rotate the mouthpiece
  3. Plug Floome into the headphone port.
  4. Follow the instructions from the application. You are now ready to measure your blood alcohol level, i.e. your BAC (Blood Alcohol Content).

Don’t forget: the measurements will be more accurate if you take the test at least 20 minutes after your last alcoholic drink.

What does BAC mean?

BAC stands for Blood Alcohol Content, it is the concentration of alcohol in your blood. High BAC levels can severely damage your physical and mental health, impair motor coordination, the ability to perform tasks involving spatial perception, and good judgement. Drink drive limits are set at specific BAC levels that vary from country to country. If you violate such limits you might incur civil, criminal and/or administrative charges provided for by the law of these countries.

Is Floome compatible with my smartphone?

Floome has been designed to be compatible with the majority of existing smartphones. You just plug it into the headphone port like you would do with your earphones.

Floome is compatible with all devices that run iOS7 or later,

Android 4.2.2 or later, Windows Phone 8.1 or later  (with the exclusion of CAT S40 by Caterpillar and the IPhone 7 must be used with its jack adapter). We do not guarantee the compatibility of Floome with other devices, nevertheless our R&D department will always be at your disposal to help you. For further information on compatibility, please contact us by writing to: support@2045tech.com Email object: “Compatibility with [device’s model name], [version of the operating system]” (i.e. Sony™ Xperia Z3 – Android)

Where can I buy Floome?

You can buy Floome from the dedicated website (www.floome.com).

Where can I download the Floome application?

You can download the application on your smartphone from the App Store, Google Play and Windows App Marketplace. You can also request the download link on our website.

Does the application collect personal data?

To function accurately, Floome links your data (i.e.: your physical data) and the results of BAC measurements to your Floome account. We consider your privacy to be of primary importance.

For further information, please read the application’s Privacy Policy.

Are Floome’s measurements accurate?

Yes. Thanks to its technology, Floome will provide you with accurate estimates if compared to similar products on the market. Indeed, Floome has a margin of error of ±0.075 g/L (BAC ratio: 0-1g/L, the accuracy of the product is measured through bench tests whose protocols are kept by 2045 Tech). Therefore, we suggest you to read the Terms & Conditions carefully to know more about technical issues and physical conditions that may affect the device’s performance.

Terms & Conditions

Can I drive if the BAC levels are below legal limits?

The application helps you compare your BAC levels with the limits set by the law, nevertheless this by no means replaces your good judgement on your ability to operate any sort of vehicle. It’s only you, not your Floome, who decides whether to drive or not, so be responsible: don’t drink and drive. For further information, please read carefully our

Terms & Conditions

What is the difference between a semiconductor breathalyser and a fuel cell breathalyser?

The sensors of semiconductor breathalysers detect the presence of alcohol, not the alcohol concentration in your blood. Moreover, semiconductor breathalysers are more sensitive to a wide range of volatile compounds (such as those contained in onions, cigarettes, nail varnish removers, etc.) affecting the accuracy of measurements. In contrast, fuel cell breathalysers (like Floome) detect alcohol by burning alcohol molecules with oxygen, generating a specific amount of current for every ethanol molecule detected. This makes fuel cell breathalysers the only professional and reliable ethanol detector in existence.

Is it true that Floome works without batteries?

Floome’s technology allows you to take about 3000 tests (or 10 years) with one single watch battery. With such a long lifespan, you will never need to worry about changing the battery.

Can my friends try my Floome, or is it for personal use only?

Floome uses the physical data you enter about yourself in order to enhance the accuracy of BAC measurements and provide you with personalised feedback. So, when letting your friends use your Floome, please consider that the results shown can be less accurate. For further info, please consult the

Terms & Conditions

Where should I store Floome?

Preserving the breathalyser’s sensor is of critical importance in order to allow Floome to perform very accurate tests. To preserve the sensor, Floome must be stored in a dry place with temperatures between 0°C and 50°C and it should be used in environments with temperatures between 10°C and 40°C.For further information, please read our

Terms & Conditions

Do I have to protect Floome from contact with liquids? If so, why?

Yes. Always keep Floome away from water or other liquids as it contains electrical circuits, which could be damaged. Also, if wet, the sensor may get mis-calibrated, thus providing you with inaccurate measurements.

What is covered by Floome’s warranty? Can I return the device?

Every purchaser living in an EU country has the right to return the product within 14 working days from receipt of the good, by sending a written communication to 2045Tech, following the instructions contained in the Terms & Conditions.
