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 provides a complete tool kit to make pool care easy.

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.

Verdict

The call

The clearest difference is review sentiment: LoyalAI at 73% against Pool's 22%. LoyalAI also leads on price (Free vs $4.99) and update cadence (weekly vs every 5 weeks). Pool's advantage is in-app purchases (none vs 10) and ratings volume (629 vs 13). On ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Pool holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Pool has 629 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 22% of Pool's written reviews are positive against 73% of LoyalAI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pool ships an update every 5 weeks, LoyalAI weekly. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
