There are many new tools to help engineers do their jobs, and today’s technology is making them smaller and more convenient. First were handheld calculators and computers, but now it’s the smart phone. One of the most popular smart phones today is Apple’s iPhone. The iPhone’s ability to run applications (apps) has made it famous for social media and games, but there are many other apps with more practical uses.
The following is a list of apps for the iPhone broken down into categories that fill many of the needs for today’s engineers. As with any list, this one is sure to be incomplete because new apps are added every day. All these apps can be found on the iTunes Store from within iTunes, available for free from Apple. If you choose to acquire any of the apps listed here, be sure to read the reviews before throwing down any money. Many of these apps range in price from free to just a few dollars, but some can cost hundreds of dollars.
Also, look carefully at the description because some programs only work with certain models of iPhones, while others require software installation. Sometimes the app is free and the computer software must be purchased, or vice versa. Despite these pitfalls, many useful apps can be found for free or at a reasonable price, so happy hunting.
Audio apps span the range from SPL meters and tone generators to time code calculators and generators. Comrex has a remote audio app that ties into its studio codex. There’s also reference material including a list of all professional microphones and recording terms.

Viewing: vueCAD, Drawvis, nvDXF, Drawvis Free
This category comprises circuit simulations, calculators, training and glossaries. Some apps are limited to just one calculation or set of data, while others contain a wide range of information, which usually cost a few dollars. But a few dollars is far less than the cost of a book on the subject.

Keeping up with the latest technology and software is not an easy job, but it’s much simpler with these apps. Under security are apps that can store your passwords for you as well as glossary of security terms. Other apps will scan for open ports on the network alerting you of potential security risks. There are apps that help decode IP packets and list common ports and their names, and others will calculate subnet addresses and ping devices on the network. Under reference, there are books on IT security that fit in your smart phone, and remote desktop apps allows you to remotely control your computer and/or server from anywhere in the world. Most of these apps only control one type of OS, and so they have been marked: Windows (W), Macintosh (M) and Unix (U).

These apps assist in aiming your dish by using the built-in GPS to find your current location or by using maps to pinpoint any location on earth. Some apps superimpose the satellite names over the video from the built-in camera when pointing it at the sky. This can be very useful because it can tell you if the satellite in question can be seen or if obstacles will block the sightline to the satellite.
