I came across this by accident and is one of the best things I have ever downloaded. Let's just say .99 saved me from driving home that night and other friends I have shown this to as well. I've come across allot of other apps like this but this one is the easiest to use and most accurate results. Great Buy!

Great App! Easy to use and fun at the bar!!! Saved me last night from driving home and it's good because we got pulled over a quarter mile from our house! Thank you BAC Reader!!!

I think this software is awesome. It helps me when I think about driving after having few drinks. I used this application and then used a breath-a-lizer and the answer was almost perfect. This App is a must have.

There are a lot similar BAC calculator applications out there but you can tell this one was really thought out and every fine detail is done flawlessly. From the logos to the no frills, very easy to use wheel calculator, this application is almost a piece of art. Every aspect of the app serves a function and does so in a very intuitive manner. Very, very well done application.

Very fast and Ez to tell my BAC "Very nice"

Very entertaining at the bar. Cool to bee able to easily quantify how wasted you feel. Already started gambling with friends on who can guess closest to actual BAC. Obviously gets more difficult as night goes on. Definitely worth the .99$

It assumes you change your weight and sex everytime you load the app or refresh. Default is 160lb male, I'm 200. Everytime I load the app it forgets how much I weigh and assumes a completely new person is running it! It should 1) remember sex and weight between loads/refreshes 2)if I reload the app within an hour or so, KEEP the last settings cuz I'm probably only going to take it up a beer and maybe alter the time. I didn't have a sex change or change my weight during that time!!! 3) why require a button click to calc? The formula isn't so difficult that it couldn't recalc as you change the settings and show at the bottom. It adds an extra unnecessary step. The devs need to recognize the typical use cases (same person, just new drink or time info) between uses so their decision to always revert to defaults is rethought. (I have a degree from MIT in Human-Computer Interaction. This app is nice but could be great!)

Not bad. Unfortunately it is useless where I live, because we have 0.0 BAC Law for driving. Otherwise it can save much money, I think.

This seems to be the best BAC calc. available currently. It is very easy to use. Memory for the last variables used, especially weight, would be a plus. This calc produces lower results than other tests and charts that I have used, but I've never compared any of my results to an actual blood test, so this app could be accurate. It does seem low to me though. I definitely would never use this as a guide for being sober enough to drive, just as the author indicates.

This app will save many of us "sippers" from thinking we can drive home as well as tons on insurance, etc. Very nice layout, would like to see ability to save information such as sex/weight. I would also like to see local laws of what percent puts you over the limit, so by adding a state legal limit database and pulling from that based on the state you select. Very nice simple interface!
