What Is a Rugged Device?

A rugged device is a device that can be exposed to harsh conditions without suffering from damage. Rugged phones can handle shocks, impacts, high temperatures, humidity, moisture, and much more without consequences. Some devices can even be used in hazardous work environments where concentrations of vapors, mists, and gases can be present.

Manufacturers can’t just say a device is rugged without proof. Two rating systems are often used to determine a device’s ruggedness: IP and Mil-Spec. IP ratings show a device’s resistance to dust and water. Mil-Spec ratings prove the device has passed rigorous tests and can be used in military applications.

Why a Construction Worker Needs a Rugged Phone

Construction sites are often noisy, dusty, and dangerous. While regular phones can be used in such conditions, they typically don’t last long. This is because standard smartphones aren’t built to survive exposure to extreme conditions. They can easily break or suffer from internal damage due to moisture or humidity.

Rugged work environments like constructions sites require rugged phones. Such phones will survive exposure to harsh conditions and ease communication with your coworkers, thanks to their unique features.

Plus, many rugged phones have additional options that construction workers can find useful, like thermal imaging or enhanced hygienic properties.

Five Best Mobile Apps for Construction Workers

Here’s a short overview of some of the best apps for constructions workers:


FingerCAD enables you to create technical drawings on your phone using your fingers. The app allows you to draw homes, decks, floor plans, or anything else that can be designed with a CAD application. You can save your drawings, share them with coworkers, and print them out.


PlanGrid is an excellent drawing-sharing app. It works by publishing drawings to a cloud that can be accessed by all team members. That way, everyone stays in the loop regarding recent changes.

OSHA Heat Safety Tool

This app offers recommendations for protective measures that keep workers safe. It displays the current heat index in your area and reminds you to drink water, take breaks, plan for emergencies, and more.

Handyman Calculator

Handyman Calculator is a simple app every construction worker needs. It helps you calculate materials, organize your time, track invoices, write to-do lists, and much more.

Carpenters Square

Carpenters Square helps you square foundations, walls, or floors. All you need to do is fill in the blanks, and the app will do the rest.

Top Five Construction Worker Add-On Accessories

Construction workers can take advantage of numerous add-on accessories:

Memory Card

If your phone’s storage is full, its performance will decrease. Fortunately, this can easily be solved with a memory card. These cards are affordable, easy to use, and can store hundreds of files.

Bluetooth Earphones

Talking on the phone can be tricky when you’re doing something with both hands. If you often need to make phone calls while working, consider purchasing Bluetooth earphones and talk hands-free.

Thermal Imaging Attachment

Construction workers use thermal cameras to diagnose issues and ensure proper installation. Although their efficiency is indisputable, thermal cameras are often very expensive. Fortunately, FLIR offers a unique and cost-effective solution: thermal imaging attachments that mount on your phone and cost much less than regular thermal cameras.

For an affordable thermal-imaging rugged smartphone, check out the Cat S62 Pro.

Power Bank

Running out of battery at work can be frustrating and inconvenient. With power banks, this is no longer an issue. These small, portable devices ensure you don’t run out of battery when you need it the most.

Cell Phone Holster

Since communication is essential on a construction site, you need to be available at all times. If you keep your phone buried in a toolbox, you’ll have trouble hearing it, especially with so much going on around you. That’s why a cell phone holster may be a good investment. It’s convenient, affordable, and prevents you from missing an important call or text.
