About this app

PoolMath makes swimming pool care, maintenance and management easy by tracking chlorine, pH, alkalinity and other levels to help calculate how much salt, bleach and other chemicals to add. 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
• Bleach Price Calculator - Find the best deals on bleach easily
• Summary page with test and chemical log insights and totals
• 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

This is a great app if you follow the Trouble Free Pool Care method. Easy logging of test results, chem adds, maintenance, and expenses. For the folks who complain about the $8 annual fee: if you care about your pool and proper maintenance thereof, that fee is well worth it. Some improvements I'd like to see include: - theoretical new level based on last reading and addition - plotting! - custom of drop down choices ( e.g., so many chemicals I would never add but have to scroll through)

This is an excellent app for calculating correct chemical levels for your pool and knowing what to add to balance things. A cheap yearly subscription gets you intuitive logging and maintenance reminders. Most importantly though, the app is actively supported by the TFP community. You'll find lots of useful information via the Pool School link, and be able to consult with experts on all kinds of pool care subjects when you run into issues.

In theory this app sounds great, and I really want to love it. However I find it incredibly frustrating that updating any settings are locked behind the paid feature. My pool settings are stuck at what they were the first time I tested it, before making adjustments. I'll probably still use it to help calculate chemicals, but not being able to update any of my pool settings unless I pay a subscription for the app means those options will continue to be locked to me. Perhaps if I had the ability to update settings but not save history on the free version, I would be more inclined to use the app more and eventual subscribe if I find it worth it, but as it is the app is too restricted for me to explore it enough to justify a purchase.
