Mobile smartphone technology has redefined how we live and work, with Apple’s iPod and iPhone leading the way.

Using various downloadable applications, those who must travel for a living can find that their offices are as close as their back pockets. But is the aquatics industry too specialized for this kind of portability?

The answer, fortunately, is "no." A number of applications are designed to make your job as an aquatics professional easier. If you have an iPhone or iPod Touch, check out these handy titles. Some similar apps are available for the Google Android.

Pool Calculator

Price: $4.99

Developer: Jason Linhart

What it does: This app calculates swimming pool chemistry, telling you exactly how much of each chemical to add to keep the water in balance. More than just a fancy test strip, this app features recommended ranges for chlorine (FC), raising/lowering pH, total alkalinity (TA), calcium hardness (CH), stabilizer (CYA), salt, borate and the Calcium Saturation Index (CSI). Measurements are given in U.S., metric and imperial units.

HowsMyWater

Price: $5.99

Developer: pSiFlow Technology Inc.

What it does: After capturing test strip results with the iPhone’s camera, this app uses image analysis to create customized treatment plans for water. (Manual entries using the iPod Touch also can be done.) Water treatment recommendations are based on Association of Pool & Spa Professionals guidelines, and the app will keep a history of treatment recommendations.

Saturation Index

Price: $3.99

Developer: InQ Mobile Apps, LLC

What it does: Created specifically for pool technicians, pool facility managers and DIY pool owners, this app calculates the Langelier Saturation Index using National Swimming Pool Foundation calculations.

Price: $6.99

Developer: pSiFlow Technology Inc.

What it does: LaMotte Co. announces the new Insta-LINK App program, which allows smartphone users to photo-scan the company’s Insta-Test 3 pool and spa test strips, and eliminates the need to visually determine slight color variations.
