Smartphones running Android by Google or iOS by Apple serve for many things: ordering a taxi, finding your way in an unknown area, checking the time, and much more.
But how about telling us how drunk we are? It's always good to have this information on hand to avoid a nightmare night.
What you need, then, is the BACtrack Mobile Smartphone Breathalyzer, a gadget that syncs with your smartphone to report the user's level of intoxication.
The device has a fuel cell sensor (the same one used in hospitals and law enforcement agencies) to measure the alcohol concentration in the blood.
The interesting thing about the service is that it is capable of informing you within how long your blood alcohol content will return to 0.0% and of sending your results via SMS or social media.
You can get it for $79 on Mashable's website.
