How To Use

TrackBAC is comprised of 4 tabs or views, each dedicated to a particular task. Most of your time will be spent in either the Track tab (for recording drinks) or the Analyze tab (for reviewing your consumption):

Click on one of the thumbnails below to learn how to use each tab:

Step 1: Setup

Use this Tab to setup TrackBAC - you'll only have to do this once as TrackBAC will automatically open at the Track tab once your settings are configured. Enter your weight, gender, legal limit and target BAC.

You are now all ready to go, switch to the Track Tab to record and monitor your drinks.

Step 2: Track

Use this tab to record and monitor your recent alcohol consumption. Whenever you have a drink, register it with TrackBAC. Use the drink picker to select your drink, adjust the volume and alcohol percentage (if required), and tap Add to add it - you'll see your selected drink appear on the graph display. The graph shows your drinking history for the last hour - you can scroll left or right see before or after that.

Remember to tap:

The graph display

The blue line on the graph represents your BAC. You'll notice that whenever you add a drink it goes up. Conversely, when your stop drinking (or stop recording) you'll see it gradually come down. If you scroll forward (into the future on the graph) the BAC line becomes dashed - this is your projected future BAC. If you keep scrolling forward you will eventually see your BAC metabolize to 0.

The red line on the graph is your configured Legal Drink Driving Limit. You'll be warned when you go over this.

The orange line on the graph is your configured target BAC. Note, the target BAC won't get shown in the case where it is the same as the legal limit.

The BAC text in the top-right-corner is your current estimated BAC - shown in yellow for when your under the limit and red when your over.

The indicator text in the top-left-corner is a guide as to how many units of your currently selected drink you can consume before you exceed your target BAC.

Adding drinks retrospectively

Drinks by default will be added at the time you tapped Add. However, don't worry if you forget to add a drink - you can add it after the fact. Simply tap add to add a drink and then select and drag it to the correct time - you'll see the drink outlined in a yellow circle with the time highlighted as you move it. Alternatively, scroll the graph to the correct time and then tap Add - the drink will get added at that time. You can adjust it by dragging it around.


The ticker at the bottom of the display lists out the symptoms of alcohol intoxication and impairment levels for your current BAC. You'll see a warning here if you go over the limit.

Underneath the covers TrackBAC will store your drinks on your device. So you can close TrackBAC in-between drinks safely. Then, when your ready to review your consumption history open TrackBAC and switch to the Analyze tab.

Step 3: Analyze

This tab shows a detailed statistical breakdown of your drinking so far. Use it to:

The control at the top switches the display between a weekly report mode and a daily report mode. The weekly report mode shows your drinking history for each week, the daily report mode shows your drinking statistics for each day. The arrows on either side are for moving back and forth in time - to see previous weeks and months.

The vertical drinkmeter at the top-right-corner gives you a quick overview of your progress - if your drinking under your limit it will be mostly blue (for being abstinent/sober) or orange (for staying under the limit). If your drinking over it will be mostly red. For example, if you see this, it means you spent half you time under the target BAC and half your time abstinent.

The weekly report mode

This weekly report mode gives you a breakdown of your drinking so far on a week-by-week basis - including:

  1. The total number of drinks consumed.
  2. The minimum, average and maximum weekly BAC.
  3. The number of days for each week that was spent over the limit, under the limt or abstinent.

The dates along the x-axis of the graphs are for each week ending in that date. (Note, a week is 7 days and runs from monday thru to sunday)

The first graph is the # Drinks Consumed graph and shows the number of drinks you have consumed for each week.

The second graph is the BAC graph and shows your minimum, maxumum and average weekly BAC. Note, that if you only drank in one day of that week the minimum, max and average will be the same.

The third graph is the Weekly roundup graph and shows the number of days for each week that was spent over the limit (in red), under the limit (in orange) or abstinent (in blue). The goal is to abstain from drinking or to drink under your target BAC as much as possible. If you see red bars for every week then you are consistently drinking over your target BAC

For example, if you see bars like this, then that means that in the current week so far you abstained from drinking for three days, drank over the target BAC on one day and drank under the target BAC on the other.

The daily report mode

The daily report mode gives you a breakdown of your drinking for each day, including the total number of drinks consumed and BAC levels. On the graphs, you will see the days of the week along the x-axis. Remember, you can see previous weeks by tapping the previous-arrow button at the top of the page.

The first graph is the # Drinks Consumed graph and shows the number of drinks you have consumed for each day of the week.

The second graph is the BAC graph and shows your BAC level for each day of the week.

Data Management

The final section on the Analyze tab is for cleaning-up your data. TrackBAC will keep your drinking history for as long as you want it too. However, if your uploading or exporting your data elsewhere then you may want to periodically clear it out. To clear, select one of the following options:

Then tap the yellow clear button to remove your selected data from the TrackBAC history. Note, that if you want to be more selective in which drinks are removed and which are not then you'll have to use the Track tab and the Clear button. (See above).

Step 4: Export

Use this tab to upload or export your drinking history to Google Docs or Email. This is useful if you want to perform more sophisticated analysis using 3rd-party tools or if your data is being collated together with other TrackBAC user data.

To configure your export:

Note, if you're exporting to Google Docs, then you must have a Google login setup. Configure your google id and password in the Google id and password fields. These will be used to authenticate with the Goodle Docs server when your data is exported.

Configure what data will be exported:

  1. Summary will export the number of drinks consumed and BAC for each day.
  2. Drinks will export your actual drinks - description, time drunk, volume, alc % and BAC level.

The name of the CSV export file is configured beneath the data selection. You can override the default file name by tapping in the file name text box and entering your new file name.

To preview your export data, scroll to the preview pane at the bottom of your page. There you will see a list of data to be exported.

If your satisfied with your configuration, you can now export. To export, tap the yellow export button. If your exporting to Google Docs, your data will be uploaded as a CSV textfile to your designated google docs account. The name of the file is configured in the textbox above the google id field. If your exporting to Email, TrackBAC will open the Email application with a new email message and the export data placed into the body of the email.

Note, that exporting to email will exit TrackBAC and open the iPhone email application.

Export errors

Sometimes you may get an error when exporting to Google Docs. Don't worry, this happens occasionally. If its an authentication issue then check your google id and password are correct. If its a network issue, then ensure you have wi-fi access then try exporting again.
