Great product, fine app

When I first opened, I had to read the manual to understand switching between the app mode and the manual mode. Not sure why it isn’t just one mode together. Additionally, the app doesn’t seem to be optimized for the newest iPhones. I have an iPhone 11 and when I get it connected to the app there is an option at the top to “swipe to test your friends” but it’s sorta hidden under the top notch and no amount of swiping works. Overall looks like a clean app, just needs some optimizing and I love the device!

Fantastic and a must have for responsible drinkers

This is fun to use at home to see exactly how well my body processes alcohol. I love putting those double shots of whiskey back, and I always seem to hold my drink above the rest of them in parties as well. However, now that I can actually see where I’m at in the ‘real’ world... I should probably start admitting that I’m more inebriated than what I truthfully feel that I am. I was stupid to trust my feelings in the past (now all those drives I took, etc... I am filled with regrets even though nothing happened). Also this is a MUST HAVE FOR PARTYING AND BUSINESS TRIPS. This is hilarious to use with friends and coworkers and after all the laughs your group tends to make better decisions without needing to be stick in the mud in the night. Using the BACTrack breathalyzer must have saved lives by now.

I’m a huge heavyweight when it comes to handling many, MANY drinks, but this breathalyzer doesn’t lie, I’m more human than everyone else or even I think I am. Drink responsibly folks. Cheers! 🥃

Good app but misleading

The only reason this app didn’t get 5 stars is because of the heath kit feature. It says it will sync to health kit and I know for a fact it used to when I had purchased an earlier model but I stop using the app for about 2 years and just bought a newer model and when I used the app I found out the health kit sync feature isn’t supported anymore even though it says in the settings that it is. This is very disappointing as this is one of the main reasons I bought the model that uses the app I hope they will start updating the app regularly like they should be at the time of this review the last app update was almost 6 months ago...
