United StatesLooking for help with calculations for your swimming pool or hot tub chemistry maintenance? The Pool Calculator does all the math for you, making chemical testing and treating your pool or hot tub a breeze. Pool Calculator is easy to use, and tells you exactly how much of each chemical to add to keep your water in balance and crystal clear. No more puzzling over complicated charts and formulas. Bring your iPhone or iPad out to the pool and have all the chemical information and calculations you need right at your fingertips. Pool Calculator works offline and online, so if you have poor internet reception by your pool, you’re still able to get test results. Pool Calculator provides a complete tool kit to make pool care easy. You get: • Chemical Calculator • Pool Volume Calculator • Chemical Effects (What-if) Calculator CHEMICAL CALCULATORS You can use whichever test strip or test kit you prefer for testing your pool or hot tub. Pool Calculator provides calculations for: - Chlorine (FCl) - Raising pH - Lowering pH - Total alkalinity (TA) - Calcium hardness (CH) - Stabilizer (CYA or cyanuric acid) - Salt - Borate (Borax) - Calcium saturation index (CSI, similar to LSI) RECOMMENDED CHEMICAL RANGES- USE OURS OR DECIDE YOUR OWN With Pool Calculator, the recommended ranges for your chemicals are based upon whether you have a pool or hot tub, and the surface material (plaster, vinyl or fiberglass) of your pool or hot tub. You can choose from several pre-defined ranges or customize based on your or your pool pro’s preferences. POOL VOLUME CALCULATOR To keep your swimming pool or hot tub at its best, it’s important that you accurately calculate your water volume. All of the chemical balancing recommendations you receive from the Pool Calculator are based on it. You can calculate the volume of your pool in metric units (liters) or in imperial units (gallons). The Pool Volume Calculator can be used for: • Rectangular Pools and Hot Tubs • Oval Pools and Hot Tubs • Round Pools and Hot Tubs CHEMICAL EFFECTS CALCULATOR “What if” analysis for adding chemicals to your pool or hot tub! Ever want to know the impact of adding a given amount of Chemical has on your swimming pool or hot tub chemistry? The Chemical Effects Calculator calculates the impact adding a specific amount of chemical has on your pool chemistry. It does this not only for the primary purpose of the chemical, but also on the other important measurements for your pool. For example, adding Trichlor not only raises your Free Chlorine, it also increases your Cyanuric Acid, lowers your pH and increases your Salt. Adding Cal Hypo raises Free Chlorine, and also raises Calcium Hardness (CH) and Salt. With the Chemical Effects Calculator, you can measure the effects on pool chemistry of adding a given dose of: • Bleach • Trichlor • Dichlor • Cal-hypo • Lithium Hypochlorite • Chlorine gas • Muriatic Acid • Dry Acid • Washing soda • Soda Ash • Borax • Sodium Tetraborate Pentahydrate • Boric Acid • Caustic Acid (lye) • Baking Soda • Calcium Chloride • Calcium Chloride dihydrate • Stabilizer • Liquid Stabilizer • Salt PoolCalculator can be used for in ground or above ground pools, spas and hot tubs, chlorine or salt pools, and a broad range of surfaces.

DO NOT BUY!
Waste of money. Company is in Nigeria. Wonder how much experience they have with pools - and with pools in our latitude. Paid $5 for this app. - It does not allow addition of a second pool or spa even though the one added is called “first pool.” If you have two units, the size must be reentered for each one if a different one is tested next. - And there is no tracking of history. Each test is entered separately with treatment suggestions given for that one instance. No way to know what I did last week or last month. -Have two stars because it does calculate pool size and gives suggestions based on the chemicals you buy (assuming “washing soda” is the same as sodium bicarbonate or baking soda).
United StatesLifesaver
Moved to the country and built a pool. No one wants to come out and service it because the round trip is too long. This has been an incredible tool. First time pool owner. I have a sparkling blue pool all summer long!! Highly recommend!!!
United StatesFair but lots of room for improvement
I am not sure how this app beats a piece of paper. I use an Excel spreadsheet to track my testing results and chemicals to be added to the pool. My objective is to develop charts to show the apparent interaction over time between chemical changes Ph, Cl, ALK etc. This app doesn’t appear to keep any records to compare one week vs the next. So I ask, why not us s piece of paper. This is junk.
United StatesData entry
After entering data for FC I select done; it reveal a ; it takes me to the main data screen then show no data has been entered. Unless you enter 1-5 it doesn’t save the information you entered it instead shows invalid number entered error. I wish my free Chlorine was between 1 to 5 ppm but it’s not.
United StatesWater temperature missing
Are use this for a few years now, and I’d give it five stars however, this new version has deleted water temperature setting which affects balancing of chemicals.
United StatesUpdate Bleach Percentage
The only gripe I have is that it doesn’t have the new 7.5% Clorox Disinfecting Bleach as an option in the “Effects” tab. If this gets updated it’s an easy 5 Star App.
United StatesCovers All Bases
The App is great. It also me to use alternative chemistry in my pool. I don’t have to buy chemicals from a “pool” store. I mostly shop the grocery store and the local big box stores.
