Caffiene Zone Monitors Your Caffeine Intake; Alerts You to Maintain Optimum Buzz

By Jason Fitzpatrick on February 15th, 2012

iOS: If you enjoy caffeinated drinks but still wants a goodnight’s sleep, you need Caffiene Zone–a free application that helps you monitor your caffeine consumption to maintain maximum alertness without jitters or sleeplessness.

How does it work? According to the research team behind the application:

Caffeine Zone™ 2 is an iPhone app that monitors, predicts, and displays a user’s caffeine level in real-time based on a pharmacokinetic model and the user’s input of when they consume caffeine. It can be used as an educational tool to teach how to use caffeine products wisely and effectively. It was developed by the ACS Lab at the Penn State University and spun out using a small company with permission of ONR and Penn State. It is based on research sponsored by ONR.

Caffeine Zone™ 2 users can enter their caffeine consumption and the app generates a line chart of predicted caffeine level for the next 24 hours. It also shows a cognitive active zone, an area of level where most people will feel active, and sleep zone, an area of caffeine level where most people will be able to sleep. These values are adjustable. These zones can be changed to represent individual differences.

In essence, you plug in your vital stats (like weight), the caffeine you’re consuming, and then Caffeine Zone goes to work, calculating the rate of burn and the optimum time for you to refuel with more coffee, tea, or cola.

The app is available as a free ad-supported release and a $0.99 ad-free release. Hit up the link below to grab a copy for your iOS device.
