    Default Best iPhone App for Monitoring Alcohol Consumption

    Can somebody please recommend the best app for monitoring alcohol consumption in terms of staying below 0.05.

    Drink Tracker is great, I'll be doing a review as part of the Apps for Alcos series.

    all the appz i've seen so far aren't that bad but i'd like to see an app that lists more drinks that r common in Oz so if you were to go out, you'd have more of an Ozzie selection and it'd be easier to manage your selection and also the BAC limit in some apps aren't 0.05.

    Not wanting to sound like a troll but given that the iPhone has no method for actually checking your blood/breath (that I know of at least...!) would you really trust to some basic calculations to try and estimate such a thing?

    What if it says you're at 0.04%? Even if an app has controls for things like 'large lunch/small lunch' it will never cover the minutia of factors that can have a significant affect on your absorption rate (starchy food, tiredness, weight, fat ratios, drinking speed etc etc).

    I wouldn't trust the 'spirit level' apps when hanging a door and driving is a vastly more serious business. I have always liked the basic rule whereby if you have to think about it you're over!

    Good point FreqNoize which is why I specifically set DrinkTracker up so that you weren't locked in to a pre-determined list of drinks. The drinks list is fully customisable and you can add all your own faves (even your own home brew) so that they're immediately at hand whenever you need them.

    DrinkTracker uses exactly the same calculations that allow the police to calculate your blood alcohol content from a breath alcohol reading. The science is very solid and the Stadl algorithms are used in all sorts of forensic work for BAC re-calculation and modelling.... and it's definitely way more accurate than trying to do it in your head after a few drinks.

    Just on the point of the other factors involved:

    Weight and fat ratios - you enter your height and weight into your profile so, in combination with your age and gender, your BMI is taken into account in the calculation.

    Drinking Speed - you enter them into DrinkTracker at the same rate that you drink them so it wouldn't be an issue.

    Tiredness - Doesn't affect your BAC, it just changes the way your body reacts to the presence of that particular amount of alcohol. 0.05 is 0.05 regardless of whether you're tired or not.

    Food - Drinking on an empty stomach dumps the first 2 drinks straight into your blood stream and you feel the effect sooner, but the metabolic transfer rate stabilises after that and things have caught up by drink #4 - your BAC will then be pretty much in line with what it would be if you had eaten. There is a lingering effect on your limbic system throughout the drinking session from that first headrush but whether you've eaten or not you still have a fixed amount of alcohol in your body. Feeling drunker is more due to the effects of not having eaten (low blood sugar, metabolites, etc) and this will also show up as a worse hangover, for exactly the same reasons. In an empirical sense 3 bourbons is still 3 bourbons whether you've eaten or not.

    Starchy Food - Type of food doesn't matter since the presence or absence of food in your stomach will simply determine whether the pyloric valve at the bottom of the stomach is open or closed (it's closed when the stomach contains food so that digestion can happen). If it's open then the alcohol will move straight into duodenum which does a better job of absorbing alcohol than the stomach lining, and hence a faster initial transfer rate into your bloodstream, but that slows down after a bit.

    Pretty much the bottom line here is that the factors that DrinkTracker doesn't take into account are 10% to do with the effect on your actual BAC and 90% to do with the way a given amount of alcohol affects your own perception of your own level of intoxication. Just because 6 bourbons hit you harder today than yesterday doesn't change the fact that you've ingested 180ml of a 37% spirit, and have a BAC of 0.11%, you just feel drunker for a range of physiological factors that heighten the impact of that amount of alcohol on your brain. How drunk you are and how drunk you feel are 2 different things.

    I think the key is to allow for a large margin of error.
