Are you one of those people who doesn’t know which cup of coffee should be the last one? Well, if you’re looking to do something about it, the US army is developing an app that could have a potentially life changing effect on you!

Sure, caffeine helps you stay awake and also makes you energetic, but are we really gonna believe that none of us abuse it on a daily basis? There’s a scary amount of symptoms associated with over using of caffeine.

The U.S. Army is an avid lover of coffee and it uses large amounts of coffee to keep it’s soldiers well energized. In an effort to keep staff and soldiers awake during long nights and guard shifts, they commissioned research to determine the exact, most efficient use of caffeine.

"We found that by using our algorithm, which determines when and how much caffeine a subject should consume, we can improve alertness by up to 64%, while consuming the same total amount of caffeine," said Jaques Reifman, PhD, a senior research scientist and director at the U.S. Army Medical Research and Materiel Command. "Alternatively, a subject can reduce caffeine consumption by up to 65% and still achieve equivalent improvements in alertness.”

The recent study was presented in the peer reviewed Journal of Sleep Research.

The study uses. Validated mathematical model to predict the effect of sleep loss and caffeine on psychomotor vigilance task (PVT) performance and combined it with an algorithm to see how much caffeine is required to keep one alert. The algorithm takes a user-provided sleep/wake schedule and maximum allowed caffeine as inputs and provides a caffeine-dosing strategy as the output.

TechLink, the Department of Defense's go-to broker for invention licenses, is already helping companies access a more limited mobile app called 2B-Alert.

This app is supposed to be going into public circulation very soon. Anyone else excited for this!?
