Caffeine

Caffeine is a small software application whose purpose is to help you estimate the amount of caffeine in your blood over the course of a day with the aid of graphs. It can be deployed on all Windows versions out there, provided that you have the Java working environment installed on the host PC.

Drop it on pen drives

The tool does not require any installation so you can gain access to its interface by running the executable file. In addition, you may keep it stored on pen drives or other similar devices so you can have it with you all the time. Plus, you may open it straight from the storage device without having to possess administrative privileges.
It is important to mention that it does not leave entries in your Windows registry so you may get rid of it using a quick deletion task of the files that you have downloaded from the Internet.

Clean layout

Caffeine sports a clutter-free environment that allows you to input the level of caffeine directly in the main window and specify the time in hours and minutes. Based on the aforementioned parameters, the program displays a graph that estimates the amount of caffeine in your blood.

Configuration settings

The application hides several tweaking parameters under the hood which can be accessed by right-clicking on the graph. You are offered the possibility to zoom in or out of the graph, automatically arrange both axes, print the graphs, as well as export the information to PNG file format.
Other important tweaking parameters worth being mentioned enable you to change the default title of the graph with a user-defined text and alter the text in terms of font and color, show or hide the title, make several adjustments to the plot (e.g. change the label, display tick labels and marks, tweak the outline stroke), enable the anti-aliased mode, and alter the color of the background.

Final observations

All in all, Caffeine comes packed with several handy features and makes it simple for you to calculate an estimated amount of caffeine in your blood.
