A Pool Math alternative for exact dosing
Updated:
Pool Math is a free, trusted calculator from the Trouble Free Pool community. If you want exact doses plus in-app troubleshooting, unlimited logging on the free tier, and a private app that works offline with no account, DoseMyPool is worth a look.
What Pool Math does well
Pool Math, from the Trouble Free Pool community, is free, dependable, and widely trusted. It calculates how much to add to hit your targets using the well-known TFP method, and Premium adds log history, reminders, and sync across devices. If that workflow suits you, it is a good tool.
Where DoseMyPool is different
Both apps turn your readings into how much to add. DoseMyPool focuses on what comes next: the safe order to add things, never-mix warnings, and step-by-step troubleshooting for green and cloudy water, all inside the app. Unlimited logging, history, and trends are free rather than Premium, and pools, hot tubs, and saltwater are treated equally.
Private and offline by default
DoseMyPool needs no account and runs entirely on your device, so it works at the poolside with no signal. If you want cloud sync across devices, Pool Math Premium offers that. If you prefer your data to simply stay on your device with no account, DoseMyPool is built that way.

FAQ
Is there a good free alternative to Pool Math?
Yes. DoseMyPool has a genuinely useful free tier: the exact-dosing calculator plus unlimited test logging, history, and trends are free. Premium adds insights, the full troubleshooting library, reminders, and equipment tracking.
How is DoseMyPool different from Pool Math?
Both turn your readings into how much to add. DoseMyPool adds the safe order to add things, never-mix warnings, and in-app step-by-step troubleshooting, keeps logging and trends free, and treats pools, hot tubs, and saltwater equally, with no account and full offline use. Pool Math offers cloud sync across devices on Premium, which DoseMyPool does not.
Can I switch from Pool Math without losing the method?
The chemistry is the same science. DoseMyPool computes free chlorine targets that scale with your cyanuric acid, balances pH and alkalinity, and shows water balance (LSI), so the numbers line up with what experienced pool owners expect. You can also bring your data: DoseMyPool imports CSV test history, free.
