PROOF™ is designed for anybody who drinks alcohol, from casual drinkers to all night partiers, with patent pending technology to help you safely consume.
PROOF™ reads alcohol molecules that naturally pass through your skin when you drink to determine your BAC levels, estimated time to sobriety, and effects of your diet, activity, and sleep on your ability to handle alcohol.
For the first time, our cutting edge technology gives you the power to track alcohol levels continuously without cumbersome or expensive devices.

Grand Prize, 1st Place in Tech, and People’s Choice at UC Santa Barbara’s New Venture competitions
$100,000 National Institute of Health “Wearable Alcohol Biosensor” Challenge Prize, where PROOF™ was tested against police-grade breathalyzers and blood samples.
Let PROOF™ tell you when you’ve had enough, so your friends don’t have to. You have all the power of a breathalyzer packed into a discreet wristband.
Breathalyzers require wait times of up to 30 minutes after your last drink to avoid false positives and can be affected by humidity. Upgrade to PROOF™, and get continuous measurement through your skin!
Alcohol molecules pass through your skin when you drink. Our patent pending technology converts alcohol molecules into electric signals through enzymatic electrochemistry to measure your BAC. Real time results are sent by Bluetooth to the PROOF™ app.
The team at Milo Sensors has put in over two years of research and development with nearly 1,000 test studies. Our enzyme-based sensor is developed in the industries of electrochemistry, in which the continuous measurement of individual molecules is crucial, and microfluidics and consumer packaging, in which disposables are the solution to reliable biosensing.
Our team of electrochemists, polymer chemists, mechanical and chemical engineers have combined their unique talents to create a new technology wearable designed for drinking.
Pair your PROOF™ with any Bluetooth compatible smartphone for easy monitoring of your BAC. The low energy Bluetooth 4.0 paired with a super efficient 12mAh lithium polymer battery allow for four days of continuous use. Bring PROOF™ with you for a long weekend getaway and forget about a charge.
Cartridges can be easily loaded into your PROOF™ wristband. On you way out, simply pop a new cartridge in for 12 hours of continuous blood alcohol readings.
Each PROOF™ cartridge lasts a full 12 hours, so you can track your BAC through your entire night out, even into the next morning. Each cartridge is loaded to the underside of the wristband and locks in magnetically.
PROOF™ allows you to continuously track alcohol levels. Enzymes present in the cartridge convert ethanol into an electric signal, which is then converted to a BAC level specific to you. With one data point per second resolution, PROOF™ keeps a constant monitor in ways that would be impossible with a breathalyzer.
Now you can go out and have fun without worrying; PROOF™ will check in when it is time.
Our cartridge measurement method senses alcohol molecules that naturally evaporate from your skin, which is much more socially acceptable than pulling out a breathalyzer in the bar or simply tallying shots. PROOF™ is the first wearable that can gain extremely high resolution blood level insights in a non-invasive way.
PROOF™ is designed to look like an activity tracker with a sleek and soft silicone band and classic style watch clasp. Suitable for drinks with friends or a business dinner, PROOF™ puts the power to quietly measure your BAC, or share with friends.
Set alerts based on your desired consumption levels, track effects of your lifestyle on how your body handles alcohol, and connect with friends.
Make a quick decision about whether or not you should have another drink. The PROOF™ app allows you to set individual limits and will notify you when you’ve hit them by a soft vibration and LED flashing lights. Next round, order a water!
Our unrivaled technology graphically depicts your current blood alcohol levels over time along with an estimated time until sober. PROOF™ also compares alcohol data with diet, sleep, or activity level to better understand how external factors affect the way your body handles alcohol. All transmission data is encrypted with industry standard Bluetooth encryption.
Monitor your BAC levels and compare with your entire friend group in the ‘Friends’ page of the PROOF™ app. Each person’s BAC is displayed over time the entire night. Choose who you share results with in the secure, permission-based pairing. With PROOF™, somebody always has your back.
Clarity Design turns great ideas into amazing products. Clarity Design has worked closely with Milo Sensors to develop PROOF™, the first wearable for alcohol sensing, from concept, design, prototypes, and now production.
How much is shipping and handling? Shipping and handling, which includes shipping the items to our offices, packing and fulfilling orders will cost:
Will you refund shipping costs if it ends up being less expensive?
Is there a warranty?
Do I have to blow into it?
No. PROOF™ senses the alcohol that naturally diffuses through your skin.
How accurate is PROOF™?
PROOF™ won $100,000 in the NIH/NIAAA Challenge Prize, where it was tested against high-accuracy blood tests. PROOF™ measures 1 data point per second over a 12-hour period, which is 43,000 times more data than a typical breathalyzer. With continuous data, you can do things that are impossible with breathalyzers, such as setting alerts to be notified at pre-designated levels and even interact and connect with others!
Can I use PROOF™ to see if I’m safe to drive?
No. Never drink and drive. Any amount of alcohol in your system impairs your judgement and slows your reflexes. PROOF™ is not intended to be used to see if you’re safe to drive.
Is there a delay between when I have a drink and when PROOF measures a signal?
Yes, it takes time between when you consume alcohol and when it travels through your stomach, into your bloodstream, and exits your skin. There is a delay that varies from person to person. The thing about diffusion is that some molecules zip through and make it quickly out of your skin and into the PROOF™ sensor, and other molecules take their time to get through the stomach. Our algorithm estimates BAC as soon as the first molecules are detected. You can expect some variation caused by what you ate, how many drinks you had, your gender, weight, and many other factors.
How long does the battery last?
Our 12 mAh rechargeable Li-polymer battery is designed to last for 4 days on a single charge.
How long does each cartridge last?
Each cartridge lasts for 6 months on the shelf, and once it’s out of the package, the 12-hour-use clock starts.
How does it work?
Science! When you have an alcoholic drink, the ethanol in that drink goes from your stomach into your bloodstream. Some of it you breathe out, and some actually diffuses naturally through your skin. Our patent-pending enzymatic electrochemical sensor cartridge converts the trace amounts of ethanol into an electrical current that is amplified, digitized, and sent via bluetooth to a smartphone, where our algorithms convert it into an estimate of BAC.
Is my data private?
Yes, absolutely. Your data is private. We will never share identifiable data with third parties. Your BAC data is for you to do with what you please.
Is PROOF™ going to tell me when to stop drinking?
No. PROOF™ is an educational tool to help you make smarter, more educated, decisions and is never a replacement for good judgement.
Did you invent the technology?
Yes! Our team of engineers and chemists created a revolutionary new patent-pending sensor technology that is the basis for PROOF™.
Will PROOF™ continue to improve over time?
Yes! We have designed PROOF™ with flexibility in mind. With each new batch of cartridges, you will see improvements in robustness, accuracy, and reliability. The PROOF™ App is designed to receive regular updates, so you will continue to experience new functionality. Even the electronics in the wristband is designed with firmware-over-the-air, so that we will be update the firmware running on the wearable to increase battery life and performance.
Can PROOF™ read other molecules coming out of my skin?
No. PROOF™ is the world’s first wearable alcohol sensor, and detects ethanol molecules that diffuse through your skin. We are excited about the potential for our technology to sense other molecules in the future!
Will there be a free mobile app?
Yes! PROOF™ comes with a free mobile app that provides you with continuous access to your alcohol data and many other features. The PROOF™ app is currently built for iOS and we are working on the Android version. We expect both to be ready when we deliver.
It is water resistant?
No, PROOF™ is not water resistant. Our electronics don’t play nice with liquid.
Is it safe to wear?
Yes, PROOF™ is built with skin-safe materials. We studied the wearables that have been around for the past decade, and chose materials that have proven to be safe and effective. The silicone band is soft and comfortable. The medical-grade plastics are designed for skin contact.
What is the range of BAC that PROOF™ measures? PROOF™ measures between 0-0.2 g/dL BAC, and displays “>0.2” for any values above that.
