Review: DrinkTracker Breathalyzer

Overview
DrinkTracker is ... you guessed it, a blood alcohol content calculator. It is well made and has some great features, but I don't know if it can stand out in an over-saturated market of similar apps. I used DrinkTracker during a recent night of drunken debauchery and it worked great tracking my level of drunkenness throughout the night. If you're looking to get pissed and want to know just how pissed you are, DrinkTracker is a good choice. Even though DrinkTracker is better than other BAC calculators I've seen and used (like the free app Last Call), DrinkTracker is only slightly better. Let's explore DrinkTracker in depth to see if it's worth the money.Features
Simply set up a profile for yourself by specifying your gender, weight and height and then start logging your drinks as you consume them. If you screwed up and forgot one or two drinks you can easily set the time to whenever you drank them. Soon you'll be on your way to being sloshed and you'll have a pretty good estimation of how close you are to vomiting. The app is well made and has support for U.S. (also Imperial) and Metric measurement systems and it also helps you find a taxi or get traveling directions for when your done. When it's time to add a new drink you can quickly look at a list of common types of drinks with standard proofs or you can go in and add your own. If you close the app and reopen it to add another drink or check your level of drunkenness, it picks up where it was and calculates for the time in between. If there's one feature that sets this app apart it's the ability to set a target BAC. Every BAC calculator is a rough estimation of how blitzed you actually are, but what's important to most people is identifying your unique happy place. Or your unique sad place if you're "that" guy. My happy place is somewhere between .08 and .12. So I set my target BAC at .08 and when I drank myself there the app offered a pop-up letting me know I achieved my goal. This is an important feature to me because, whether the actual BAC is perfectly accurate or not, I can trust the consistency of the formula to keep me at that level of being hammered.The Breakdown
The Good
I've exchanged several emails with Greg Slapp, owner of DrinkTracker, and he clearly knows what he's talking about when it comes to how pissed you are. He's been running the Web site rupissed.com for the past 10 years and it's essentially the same thing as DrinkTracker. I asked him several technical question about the app. His knowledge on the subject and quick turnaround time was impressive. One of the questions was about the "drink now" button. I wanted to know whether it assumed you've consumed the entire drink when you press the button. Should I tap the button when I start a glass/bottle or when I finish? Does it make a major difference whether you chug the drink or drink it slowly? His answer:"We tussled with that issue ourselves. As soon as you press the drink now button, all of the alcohol contained in the drink is put into the BAC calculation. Doing it when you have your first sip will cause the BAC to display over by about 0.018% initially, but by the time you've finished drinking it your actual BAC and the theoretical will be pretty much the same, since both your body and the calculated model have recorded an input of alcohol in your system, it's just that the calculation thinks it's been there a bit longer. But even from the first sip there's been alcohol for the body to metabolise so the metabolic removal kicks in at the same time in both cases. On the other hand, if you hit the drink now button when you've finished the drink, the BAC will read higher by about 0.006 because the calculation hasn't been able to take into account that the alcohol has been in your system for time since the first mouthful, and so has been partially metabolised. The downside of doing it this way is that the calculation will never catch-up because the unrecorded consumption time is never able to be included in the calculation, and is permanently missing from any subsequent BAC calculations. Pressing it when you take your first sip is the more accurate method of the two, although half-way through would actually be ideal."Another great thing about DrinkTracker is it integrates really well with the Google Maps API so you can get driving, walking or public transit directions already made when it dumps you into the Maps app. In other words, if you enter set up a list of address in DrinkTracker for places you might visit throughout your night of drinking, it's just one step to get directions and find transportation to your next destination.
