I just want to have a reading, not an ongoing history. I still haven’t gotten signed in.

Tried repeatedly to set up &!use software. It’s just a ruse to get you to sign up for paid version

I suppose this is a review of the product rather than the app. The BACtrack can very easily be fooled. My ex-spouse was sending me readings every two hours after her treatment program while my daughter spent the weeknights with her. It was working beautifully, sending me her BAC and her location, or at least I thought it was working beautifully. While I was working swingshift, she was getting lit. She was able to send me positive tests every two hours by simply turning the device around and sucking on the other side for several seconds. The device doesn’t measure CO2 or anything that might verify that what’s going through it is exhaled breath. It took me finding her drunk with my daughter in her care to figure out the BACtrack is not a reliable safeguard.

The the BACTrack with app gives a sorry error every time I’ve used it since it came out of the box.. there is nothing I can do to adjust it or fix. Waste of $140. Garbage

Terrible device, once connected to app it will not got to manual mode. If I delete app it just keeps searching. If I try to login it doesn’t recognize my login, or my email. If I turn it off remove, battery it goes immediately to app mode. Can’t return device, as it was a gift.

Download the app and created a account. Followed instructions on how to connect Bluetooth in app. (Yes my Bluetooth is turned in in settings) every time I hold the button for two seconds as it says in the manual it looks like it starts to sync but then the machine turns off. If I close the app the machine will stay on. This product is completely useless and would advise against purchasing.

Even with the newest battery, the device shuts off when attempting to connect to the app.

I have owned several breathalyzers over the years. This is by far the easiest to use. We have given them as gifts to friends that we have a hard time convincing not to drive.

Won’t connect to my phone.

I ordered this and waited for the shipment to arrive and when it finally did it did not work at all. It would turn on and connect to my phone and when I would blow into it as instructed it would send me a notification that it didn't accept my breath test and try again. I tried probably 30 times. I powered the breathalyzer down and back on again multiple times and tried breathing harder and softer and every time I got the notification that the breath was not excepted into try again. What a waste of time.
