## What is R?

Do you know your limit when it comes to drinking? Did you know that even one or two drinks can impair your ability to drive? Always plan for a safe ride home BEFORE you start drinking. 

R-U- Buzzed estimates your blood alcohol concentration (BAC) level based on the interaction of weight, gender, time you’ve been drinking and alcohol consumed. For this calculator, one drink is considered to be equal to 12 oz. of beer, 5 oz. of wine or 1.5 oz. of hard liquor. 

Use the “Need a Ride?” button to connect to popular ride-hailing services, including Uber, Lyft, zTrip and Curb.

******************

Disclaimer: This blood alcohol concentration (BAC) calculator is only an estimate and is not sufficiently accurate to be considered legal evidence. The calculations are averages, and many variables could affect an individual’s BAC level.

Food in the stomach, medications, health and psychological conditions are influencing factors and many establishments serve alcohol in portions larger than the standard drink size. Do not use the R-U- Buzzed app to determine whether you should operate a motor vehicle or other heavy equipment. It is never safe to drive after any amount of alcohol. You can be arrested for impaired driving if your driving ability is affected to even the slightest degree.

R-U- Buzzed is provided by the Colorado Department of Transportation (CDOT).

### 1/5 — Archaic! NEEDS AN UPDATE!

*2023-05-18*

The app version is down right archaic! You need to update it VERY BADLY!

### 2/5 — Will get you in trouble

*2017-04-06, version 2.1*

No differentiation between different ABV drinks. No timer, it's up to you to adjust everything. If the app goes into the background, everything is lost and you have to reenter it. Absolutely not something I want to rely on. Especially if I'm going to be drinking... which is the point of the app.

### 5/5 — Great app

*2017-03-11, version 2.1*

Great app for a general idea. It's not 100% precise but it gets you in a general area of your intoxication level.

### 1/5 — No metric

*2017-02-26, version 2.1*

Waste of time using ancient lb and oz

### 1/5 — Cuts me off at 12 beers

*2015-08-15, version 1.2*

This app is ridiculous...it cuts me off at 12 beers no matter if I've been drinking for 3 hours or 5. Not worth a download.

### 5/5 — Accurate!

*2014-09-30, version 1.2*

I used this app against a legit police breathalyzer. It was spot on accurate!

### 1/5 — Horrible

*2014-03-05, version 1.2*

Doesn't save information if you switch apps.

### 2/5 — Meh.

*2014-01-15, version 1.2*

Really? Your app can't count my drinks if my phone sleeps? A marker and my arm are more useful.

### 3/5 — App resets all values when switching between apps. :(

*2012-11-24, version 1.2*

It resets all values if/when you switch between apps.  :(  Otherwise good.

### 2/5 — Weak!

*2012-09-08, version 1.2*

Doesn't let you specify more than 12 beers
