poolcntrl
Pool ownership without the guesswork.
Test your water, get exact dosing for the chemicals you actually own, log what you added — and skip the trial-and-error.
Built for owners who’d rather just get it right.
Confidence Engine
Deterministic chemistry math — same inputs, same answer, every time. No AI guesses your dosing.
Zero-Friction Input
Test strip scan or manual entry. We pick a target, you log what you added, we update next time.
Guided Diagnostics
When numbers look wrong, the app explains why — and tells you what to retest before adding anything.
Try it on a real pool.
This is the actual chemistry engine running in your browser, against an 18,000-gallon plaster chlorine pool. Adjust readings or pick a scenario.
