PoolCheck is a free pool test strip reader and pool chemical dose calculator for backyard pool and spa owners. Photograph your test strip, confirm the readings, and get a clear dose plan: which products to add, how much, and in what order. No account and no sign-up. The app opens straight to your pool. READ YOUR TEST STRIP • Take a photo of your strip with your iPhone or iPad camera, or pick one from your photo library. PoolCheck lines up each pad with the color chart and suggests a reading for you. • Color matching runs on your phone. Your strip photos are not uploaded. • Each suggestion is marked so you can check it against the chart on the bottle. Low-confidence pads are flagged or left blank rather than guessed. • Prefer a drop kit? Type your numbers in by hand. EVERY READING THAT MATTERS • Free chlorine (FC) and total chlorine (TC) • pH • Total alkalinity (TA) • Calcium hardness (CH) • Cyanuric acid (CYA / stabilizer) • Bromine for bromine pools and spas A POOL DOSE CALCULATOR THAT SHOWS ITS WORK • A step-by-step plan for your gallons: product, amount, and an everyday measure such as "about 1½ 5 lb bags". • Adds are listed in a safe order: alkalinity, then pH, then sanitizer or shock, then stabilizer, then hardness. • Retest timing for each step, and a confirm screen so you check every number before you pour. • Your free chlorine target is set from your CYA level, not a one-size 1–3 ppm range. • Combined chlorine (TC − FC) is calculated, and PoolCheck suggests a shock toward breakpoint when it is 0.5 ppm or higher. • At-a-glance status for pH, alkalinity, hardness, chlorine and CYA, each marked low, high or OK. BUILT FOR YOUR POOL • Chlorine, saltwater (chlorine generator), bromine and spa. • Vinyl, plaster and fiberglass finishes. • Know your gallons? Type them in. Don't? The pool volume calculator estimates gallons from shape (rectangle, oval, round or kidney), length, width and average depth. • Pick the chemical brand on your shelf. Doses use popular pool-chemical brands or generic store products. • Optional shop links help you find a product online. HISTORY, WEATHER AND HELP • Every completed test is saved with the date on your device. Tap one to reopen it, or swipe to delete it. • Add your ZIP code for a short local forecast and a heads-up to retest after heavy rain. • A built-in Help & FAQ explains strip reading, CYA and chlorine, combined chlorine, and pool volume. • Send feedback straight from the app. PRIVATE BY DESIGN • No account, no password and no cloud profile. Settings, history and purchases stay on your device. • Strip photos are read on your phone and never uploaded. FREE, WITH AN OPTIONAL UPGRADE PoolCheck is free to download and use, and supported by ads on the results screen. A one-time $4.99 in-app purchase removes ads. It is not a subscription. Already bought it? Your purchase is restored automatically from the App Store on this device. WHO IT'S FOR Homeowners who test their own pool or hot tub with strips or a drop kit and want a quick, clear answer to "what do I add?" It's also a handy second check for anyone who looks after a pool. IMPORTANT PoolCheck is a reading and planning aid. Test strips are approximate, so confirm big changes with a drop test kit or your pool store. Add one chemical at a time, never mix chemicals, and always follow the product label.
