Whether or not convenient electronic devices like breathalyzers for personal use actually increase public safety, or hinder it, remains to be seen, but for now let's just say they might help.

The 'Breathometer' from Breathometer, Inc., of Burlingame, CA, says it hopes the device and app will help users drink responsibly. The device plugs into a phone's headphone jack and, once the app is launched, users blow into the device.

“Breathometer wasn’t created just to address the risks associated with drinking and driving,” founder and Chief Executive Michael Yim said, “but to help people, their friends and family, all to make smart and safer choices when consuming alcohol. Real-time BAC measurement is the first step.”

The Breathometer is "as accurate as other consumer breathalyzers on the market," says Yim.

Sarah White from technologyguide.com says the convenience is a first because the Breathometer is compatible with the iPhone and will plug into the headphone jack; then just by breathing into the device, it will display the user’s blood alcohol content. Of course, the Breathometer is not a legal gauge of sobriety, and should probably be used for general reference and curiosity only.

It hasn’t hit the market just yet, but pre-orders start today, and the device should ship sometime in July for $100. Currently, the device is still gaining backers on Indiegogo, where it’s inching toward its $25,000 goal, and where a $20 pledge will secure a device for less than the $100 retail price, but those units won’t ship until January.

One may think that such devices add to the checks and balances we all need to make informed decisions; and perhaps they may signal for some drinkers that it's time to stop, you're sobriety is compromised... and you've had too much to drive safely.

But it raises concerns too that some may think they can drink because they have this device. And as well all know, the info gained from such things only has value to someone who's still in a position to act responsibly. Some might want to push their limits instead.
