A new cellphone app may be able to tell you if you've had too many drinks. The app, called "BACtrack," uses a smartphone's camera to measure the amount of alcohol in a person's breath.

The app works by having the user blow into the phone's microphone. The phone's camera then analyzes the breath sample and calculates the user's blood alcohol content (BAC).

The app can be used to track a person's BAC over time, and it can also send alerts if the person's BAC reaches a dangerous level.

BACtrack is available for both iPhone and Android devices. It is free to download, but there is a subscription fee for the premium version, which offers additional features such as the ability to track multiple drinks and share BAC results with others.

How Accurate is BACtrack?

BACtrack is a relatively accurate way to measure blood alcohol content. However, it is important to note that the app is not as accurate as a breathalyzer used by law enforcement.

BACtrack's accuracy can be affected by a number of factors, such as the user's breath temperature, the presence of other gases in the breath, and the calibration of the phone's camera.

Is BACtrack Safe?

BACtrack is a safe app to use. It does not require any personal information, and it does not store any data on the user's phone.

However, it is important to use BACtrack responsibly. Do not use the app while driving or operating heavy machinery.

Can BACtrack Help Me Avoid Getting a DUI?

BACtrack can help you avoid getting a DUI by letting you know when your BAC is getting too high. However, it is important to remember that BACtrack is not a substitute for common sense.

If you are planning to drink, make sure to do so responsibly. Drink plenty of water, eat a meal before you start drinking, and pace yourself.

If you are ever in doubt about whether or not you should drive, err on the side of caution and call a taxi or Uber.
