User reviews

The app change sucks

You used to be able to just use the tool. Now it wants a little “TMI”….

Bring back the guessing your BAC!

I still find the app works well, but I really want to see them bring back the “guess your BAC” feature, because it is genuinely useful for building awareness about what you’re at. Please!

Doesn’t do much

The app is very unimpressive. Doesn’t do what the manual says. It’s also clunky because when you go to settings it doesn’t let you go back. You have to close and restart.

not connecting

I find myself constantly having to hard close the app every single time I want to connect it to the Bluetooth on my phone… It is very annoying and was not advertised when I purchased it.

It’s confusing

FAQ

What does the BACtrack app do?

The BACtrack app transforms your iPhone into a breathalyzer when connected to a compatible BACtrack smartphone breathalyzer. It allows you to easily estimate your Blood Alcohol Content (BAC), view safety information related to impairment levels, and track your drinking habits over time.

How does the app work with a breathalyzer device?

The app connects wirelessly to your BACtrack smartphone breathalyzer (like the BACtrack Mobile, C6, or C8) via Bluetooth. Once paired, results from the breathalyzer are communicated to your iPhone and displayed within the app, providing a modern and convenient way to measure your alcohol level.

Is the BACtrack app free to use?

The BACtrack app itself is free to download and use. However, it requires a compatible BACtrack smartphone breathalyzer device to function, which is a separate purchase. The app may also offer in-app purchases for additional features or services.

What are the key features of the BACtrack app?

Key features include automatic pairing with your breathalyzer, quick BAC estimation, display of safety information on impairment, the ZeroLine® feature to estimate when your BAC will return to zero, the ability to save BAC readings to track habits, and integration with Apple Health for data tracking.

Who is the target audience for this app?

This app is designed for individuals who own or plan to own a BACtrack smartphone breathalyzer. It's for anyone who wants to monitor their alcohol consumption, understand how it affects their body, and make more informed decisions regarding their safety and well-being.
