Keep swimming in your TroubleFreePool with Pool Math. Crystal clear algae free pool water is what Trouble Free Pool Math is committed to. Pool Math performs all the calculations you need to keep your chlorine, pH, calcium, alkalinity, and stabilizer levels balanced. Why choose Pool Math over the others? Other apps claim to make testing easy by using test strips and your phone's camera. Unfortunately, this is simply too good to be true. Test strips are notoriously inaccurate and end up costing you much more money in both chemicals and the tests themselves in the long run. Trouble Free Pool believes using a proper test kit is much easier, effective, and economical in the long run. By following these calculations the pool owner achieves and maintains crystal clear water without reliance on the often unproductive advice and unneeded expense from pool stores. Pool Math's great features include: • Calculators for pH, Free Chlorine, Calcium Hardness, Salt, Total Alkalinity, Calcium Hardness, Borates, CSI • Track Maintenance: Backwashing, Vacuuming, Filter Cleaning, Filter Pressure, SWG Cell %, Flow Rate • Track Chemical Additions • Track Weather conditions with your logs • Calculate the Effects of Adding chemicals to your pool • Bleach Price Calculator - Find the best deals on bleach easily • Summary page to see an overview of test results and chemical additions • Data backup / Export Premium Subscribers get access to these additional features: • Unlimited Test Log History Storage • Maintenance Reminders • Cloud Sync/Backup • Sync across multiple devices • Unlimited Pool / Spa Configurations • Test Log CSV Import / Export Pool Math Premium Subscription details: • Auto-renewable subscription • 1 year for $7.99 USD • Your subscription will be charged to your iTunes account at confirmation of purchase and will automatically renew (at the duration of 1 year) unless auto-renew is turned off at least 24 hours before the end of the current period. • Current subscription may not be cancelled during the active subscription period; however, you can manage your subscription and/or turn off auto-renewal by visiting your iTunes Account Settings after purchase. • Privacy Policy & Terms of Use: ## Pool Math by TroubleFreePool Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/16/c7/1d/16c71d2f-a004-7f73-6c42-76b53bde7a91/4.png/2064x2752.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/9b/6b/81/9b6b81f1-ab84-249a-a352-ff3b1ea733eb/6.png/2064x2752.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/66/ff/55/66ff55c7-357e-d81e-9989-8a24db44adb5/2.png/2064x2752.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/d3/ad/47/d3ad4744-bd56-ebdc-7566-5cca31dcecc5/3.png/2064x2752.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/4d/84/21/4d8421b4-d89e-b8ad-af53-42126a1db2aa/5.png/2064x2752.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/05/a1/ad/05a1ade0-e764-fc2d-3091-7468738d7009/1.png/2064x2752.png) ## Pool Math by TroubleFreePool Rating Breakdown in United States - 5 stars: 140 (52%) - 4 stars: 35 (13%) - 3 stars: 19 (7%) - 2 stars: 23 (9%) - 1 stars: 52 (19%) ## Pool Math by TroubleFreePool Reviews in United States ### *---- "Lost all my data" Upgraded to a new phone and lost ALL my historical data. Apparently you need to manually backup and restore data, unlike just about any modern app. Will not be paying for this any longer out of principle -- dknightx, 2025-09-25 ### ***** "Exactly what I was looking for" Worth every penny. This app is a godsend. Takes all the guess work out of keeping a balanced pool. Love the “Effects of Adding “ calculator and the “Timeline” feature. Pool school is also a great reference. -- OpenBook5, 2025-08-22 ### ***** "Best Pool App" I can’t love this app enough. I’ve been a subscriber for over 7 years. Easy to input pool test results. The app tells you what is in or out of range and gives you the amount of chemicals to add per volume and type of pool. Must have for every pool owner! -- FlyTravelRepeat, 2025-08-14 ### **--- "Logging adding chemicals doesn’t work" This doesn’t work if you log the addition of a chemical from inside the testing screen. Let you log the addition of a chemicals in suggested amount or different amount claims it saving doesn’t actually save anywhere. You must go to the home screen and log the addition separately and save all your current numbers separately. Pretty major functionality for the developer to not know doesn’t work -- MattSac, 2025-08-09 ### ***-- "Good app, but won’t sync" We cannot get the app to sync across devices. The app is still useful, but the inability to sync across devices is irritating. One adult has to be in control of all the chemicals. Other than that, the app works exactly as described and is very helpful. It would be useful to have a link for support in the app. I could not find one. -- Vickiann33, 2025-07-26 ### *---- "Bait and switch" It let me add a single log of test results and then wants me to subscribe to an app that provides basic functionality. I tried deleting the log and it still wants a subscription before allowing another log. It’s a pretty bad look for Trouble Free Pool. -- tjvfuifdticdh, 2025-07-08 ### **--- "Interface issues" Style updates seem to have made the interface buggy. When adding acid for pH, it kept displaying the wrong chemical after I selected something else, or displaying one chemical with quantities for another. -- Chuck300475, 2025-05-21 ### *---- "App is slow now" This app used to be great. It has been super slow to open lately and unusable. -- K P 2007, 2025-05-21 ### *---- "Well darn" I read where TFP said the app works with the current iOS 18.5, but I’m having the spinning wheel of death when I try to make any notes or add chemicals. I was able to successfully add my test results, but nothing past that. Please get this corrected, this truly is the best app ever. We have had a gorgeous pool every summer with the help of TFP, PoolMath, and TfTestKits. Thank you! -- Notforme300, 2025-05-18 ### *---- "Not free" After a few test results it locks you out and wants money. Not worth it -- muryder, 2025-05-17 ### **--- "Requires Subscription" I can’t update my pool’s test results after logging my first values. Entering a new log requires a subscription and there is no way to update the values of the initial log. The inability to do this makes the app nothing more than a glorified math chart, so I see no point in using it. -- Discosev, 2025-02-04 ### **--- "Change to menu" I liked it when all of the chemical adjustments needed were on 1 screen. Now I have to click into each test result to see what chemical to add. -- JZLloyd, 2024-09-29 ### *---- "Can’t use for my pool" My pool is a bromine pool. That’s not an option in this app. -- LateGleeFan, 2024-09-25 ### ***** "Stupid simple" I was a new pool owner. Still am. However I don’t feel like it. Between buying a good robust Taylor kit, this app, and some hour a week, I know how to manipulate and manage my pool to my liking. The app makes the math easy and it is verified by the results I get when I follow up after chem additions 24hrs later. Can’t be happier with the app and its results. Only thing I want added is the ability to toggle the alerts for “out of ideal range” off. If I’m setting my ideal target already, then benchmark the alerts to that,or allow us to toggle them off,or allow manual ranges to be set. Otherwise I’m satisfied. -- AR15dood, 2024-09-18 ### ***** "Less Chemicals, More Fun" This app is from TroubleFreePool which is a non-profit forum of pool owners who want to help other pool owners enjoy beautiful, clean swimming pools without using more chemicals than necessary. They are super knowledgeable and very helpful. This app helps pool owners know exactly what chemicals are needed and how much of each chemical to use. Great app for a great forum! -- Visa1976, 2024-08-18 ### **--- "Where is my fave app?" What happened in the update to my pool app? I should’ve never updated. Layout is awful. ☹️🫣 -- Maizy Ann, 2024-08-18 ### ****- "Prefer Old UI" I’m still not crazy about the new color scheme but do like that you’ve restored some of the old features like number of days since last test and target ranges, so thank you for that. But why don’t I get the smaller squares on my overview tab to show all my results on a single page without scrolling? I’m using iOS and a screenshot in the iOS App store shows it this way. Plus a friend using your android version has it this way as well. -- Wjmano, 2024-08-08 ### ****- "Latest update" Latest update has a bug. Example when trying to input. Target free chlorine it does not allow to erase the digit that is currently there and just keeps adding more digits. -- jayzee9345, 2024-07-30 ### ***** "Amazing app" Keeps my pool crystal clear, tfp is the best resource for all pool related questions -- disenfranchised5, 2024-07-29 ### ****- "Great app but lost history" I love this app. Have used it for several years to calculate and track everything for my pool. Only bummer is an update from a month or so ago wiped my history. I emailed for help but haven’t gotten a response. -- History needs work, 2024-07-21 [View all Pool Math by TroubleFreePool reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Pool Math by TroubleFreePool In-App Purchases | Item | Price | |------|-------| | Pool Math Premium Subscription | $7.99 | ## Pool Math by TroubleFreePool Discovered Keywords -
