Online breathalyzer apps work in a relatively simple way. They use information provided by the user, such as the type of drink consumed, the amount consumed, body weight and the time elapsed since the start of the drink, to calculate an estimate of the blood alcohol level (BAC). 

Some applications are even more accurate when combined with physical devices, such as those that connect via Bluetooth to the cell phone, as is the case with BACtrack App.

The great advantage of these apps is that they are practical and accessible. Unlike traditional breathalyzers, which can be expensive and are not always available, apps are available to anyone with a smartphone. 

They provide a quick estimate that can help you make informed decisions about driving safety, for example. However, it's important to understand that these apps aren't 100% accurate.

Using online breathalyzer apps has several advantages. The first is practicality and convenience, since these apps are always on hand on your smartphone, ready to be used at any time. 

Additionally, many of these apps are free or have free basic versions. Another benefit is the awareness they provide, as they help users monitor their alcohol consumption quickly and efficiently. 

However, these apps also have their limitations. The main one is their low accuracy, since they depend on data provided by the user. Another point to be considered is that these apps have no legal value, that is, they cannot replace the breathalyzers used by the police.

And finally, there is a risk that users will be given a false sense of security by relying on an estimate that may not be entirely accurate, which could lead them to make poor decisions, such as drinking and driving.

Now that we know how these apps work and the pros and cons of using them, it's time to look at some of the best options available on the market.

First of all, the BACtrack App is one of the most popular when it comes to BAC monitoring. Designed to work with the physical breathalyzer BACtrack (sold separately).

The app also offers a free function to estimate blood alcohol level without the device. The user can input data such as the amount of alcohol consumed, the type of drink, the weight and the time of consumption, and the app calculates an estimated BAC. 

Finally, it is available for Android and iOS and is a great option for both those who want more accurate monitoring and those looking for a quick estimate.

O AlcoDroid is a great alternative for Android users who want to control their alcohol consumption.

For iPhone users, the DrinkControl is a great option. This app not only calculates your BAC based on your logged drinks, but also provides graphs and insights into your alcohol consumption over time. 

Its main focus is to help users maintain control over their spending habits, allowing them to visualize trends and make more informed decisions. 

While it's more geared toward long-term tracking, the app still offers useful BAC estimates based on what you've consumed.
