App: Engineering Assistant
Developer: Mark S. Wall
Genres: Productivity, Education

Engineering Assistant contains a multitude of useful tools for the engineer, scientist, and student. Extensive units conversion, materials property database, and a free-form functions and formula database are included. The most important aspect of Engineering Assistant is that it allows you to edit and add data that best fits your needs. 

The conversion tool is linked to the materials database so that you can view and copy property data in many different units. The materials database allows variable property data, such as conductivity vs temperature. The functions database allows you the freedom to create your own project hierarchies with just about any information you want. Entries for function information can include web links, graphics & pictures, other documents, and movies. Engineering Assistant will be a welcome addition to your engineering and academic work. 

Variable property data can be plotted to the screen, then exported to a graphics file or printed directly from the app.

Create your own project tracking databases and keep all of your work, school, and home project data in one convenient place. Use DropBox to synch your data to all of your Macs. 

New easy-access buttons for quickly enabling / disabling the editing interface.  New database management tools.

Your data will remain under your control: By setting a personal password to enable data editing, you can allow others to use Engineering Assistant on your personal Macintosh, without letting them alter any of the data.

Release notes:
Compatible with sandboxing in OSX Mountain Lion.  Includes quick access to security settings.  Expanded import capability.  Plot and print variable property data.
