Maintaining your pool or hot tub chemistry can be challenging. Liquid water tests are messy and complicated and require multiple steps to perform before you can get your full results. After you fill a vial and count the drops, deciding the color match can be tricky. And keeping the bottles and comparator around and ready, can be troublesome too. Wouldn’t it be nice to have all the materials in one spot? Thankfully, AquaChek® Test Strips do just that. It’s simple to remove one test strip that has 4 reactions on it. Dip the entire strip into your pool or hot tub for a few seconds and compare to the chart on the bottle. The little pads on the strip react with the water, changing color in proportion to the concentrations all at once. After this step, typically you would need to find a dosing chart and perhaps a calculator to figure out what you need to do to the water to keep it balanced or sanitized so everyone can enjoy it again!

The question then becomes, “Now What?!” Now, that’s where AquaChek Smart can be your go to resource and provide you with what you need. Dip your strip then match the pads to the pads on your smartphone or iPad, hit Prescription and instantly you have a set of step by step directions on what you need to do!

Needs to be fixed

Tried several times to enter parameters of hot tub- each time it crashed.
The app has not been updated for 3 years or so. Developers have obviously abandoned this app.
