Top 10 Apps for EngineersApps Every Engineer Should Be Using

Engineers are problem solvers, and without the hundreds of engineering fields and sub-fields applying math, science, and technology to the applications and industries of the world, life would look very different for all of us. A wide variety of apps are available to help design professionals perform calculations, draw components, and interpret codes and standards. With increasing smartphone processing power and HD screens, modern apps are much more than simple calculators and crude graphing aids. Even superheroes take some help from tech gadgets though, right?

Technology Demands Rise With Job Growth

Engineering jobs are already some of the highest paying and most coveted jobs around. The Bureau of Labor Statistics has projected at least 65,000 new engineering jobs by 2024, with some fields like biomedical engineering showing job market growth rates of 23.1 percent.

Such growth is accompanied by a greater technology demand to help engineers do their jobs in the most efficient and effective way possible. App designers have answered that call.

Yet, it can be frustrating and time consuming to sift through all the emerging engineering apps to determine what’s of use and which best meets your job performance needs. We’ve created a top ten list to ensure you don’t miss out on some of the brightest engineering-related apps at your disposal.
