User reviews

Annoying

It’s extremely annoying that each time I open the app. I’m asked to do a survey. At least give me a month of time in between.

Liars

When I bought this product, there was no app required. Not only did it often seem WILDLY inaccurate, but on top of that, now you have to buy their product to use it. No one said it would have this Bluetooth requirement yet suddenly here it is, and it hasn’t died within a year or more of me not using it. I just came across this in a drawer. On top of that, they advertise as a bac monitor but then are so crazily incorrect. I mean read their terms of service if you want, they literally say if they’re incorrect they should hold no liability so why is the point of this product?

Thank you.

Option to delete historical results.

I use the device for different family members. The old app didn’t store historical results. The new one doesn’t appear to allow me to delete results that don’t relate to me. Would be better if they asked their customers needs

Response from developer

We will pass along your suggestion to be able to delete specific test results to our internal team. If you have any other questions or concerns, please do not hesitate to reach out to us.

Horrible

When you need it to work, the app will not connect or it will tell you you don’t have an account so you have to take an uber anyway. Probably in cahoots with uber.

Love it

I don’t drink but when I do I always test and with my kids that are now of age

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.
