As other reviews said, this really doesn't work with BACtrack Mobile reliably at all, and the company hasn't been able to fix it for five years, so there is zero hope. It takes forever to get reading on my Pixel and fails repeatedly in many amusing ways. Either it fails to connect, or the connection drops, or it fails to start countdown, or it tells you to breath without countdown and times out or it fails to transfer the result. It's really a comedy using it every single time! Closing the app and turning BACtrack repeatedly off and on will usually eventually deliver a result if you have enough patience. You may even sober up by the time it actually does. I recently got hold of BACtrack C8, and that seems to work much more reliably. Plus it has standalone mode. I would rate this four stars for use with C6. Minus one star if used with Mobile. If you haven't gotten the breathalyzer yet, do yourself a favor and get C8 or maybe C6. If you're stuck with BACtrack Mobile and this app, good luck getting the reading.

It has trouble connecting or staying connected but works well when it does. The map that shows other user readings is horrible. They haven't updated that in years. The map is peppered with old data and its no fun to view at all. They seriously need to do something with it. I have to sort of wonder how accurate it is if the app is so sloppy then why would I assume the hardware is accurate?
