Power Calculator: iPhone Video App Review

Power Calculator iPhone App Review

Reviewed by Valerie Lauer

Electricians, engineers and emergency managers, you may want to pay attention. Our latest iPhone app review is for Power Calculator, an app from Power Continuity that completes lighting and power conversions with ease, right on your iPhone.


Even with a scientific calculator, power conversions can be a pain in the light socket. The Power Calculator iPhone app converts kilowatts, kVA and horsepower with the touch of a finger. Want to know what kind of power you’re going to need in a backup generator? Choose from single phase or the less common three phase power, the correct power factor, the volts required and amperes, and you’re good to go. There’s also an entire section on lighting conversions. Never be confused by a lumens reading again with this easy watt converter function.

That’s a whole lot of calculating power in one place. Power Calculator is a comprehensive source of conversions and equations, with a healthy slew of practical application for contractors and technicians alike. Looking for more information? The app’s about section has a list of helpful links that can help you find information on diesel generators, business continuity, uninterruptible power systems and power protection.

We do wish the app had an option to collect data and export it directly. A project building feature would also be a great addition.

User Interface:

Power Calculator organizes its tools logically, in a simple list style. There’s no tedious tree system or complex navigation. Simply tap your tool, enter your information and select evaluate. It’s that simple.

The only interesting touch of design work in the app is the color coded wire and light icons that mark each section. It’s a pretty plain app, but its function is so utilitarian that we didn’t expect a fuzzy pink exterior. This app isn’t here to entertain you with goofy animations of lightning bolts; it’s here to do a job. And it does that job quite well.

Overall Value:

Best of all, this worthy tool is free to download, with no advertisements or annoying gimmicks. Simply run your numbers and go about your business without wasting a lot of time. That might explain the app’s abject simplicity. If you work with power and want a single app to help run standard calculations and conversions, you can’t do any better than Power Calculator. This app definitely delivers. Add it to your tool box, you won’t regret it.
