Pool chemistry,
finally honest.
ClearDose walks you through a complete water analysis and delivers a plain-English action plan — from your phone, poolside, with nothing to download. Brand-neutral. Safety-first. Honest about what it doesn't know.
Add muriatic acid — follow your label dosing
Shock the pool before next swim session
In range — no action needed
In range — no action needed
Note: Acid & chlorine doses depend on your specific product — check your label.

Why ClearDose
Guidance you can actually trust.
Brand-owned apps quietly push proprietary products. Generic calculators pretend every jug of muriatic acid is identical. ClearDose does neither.
No brand agenda
ClearDose has no products to sell. Every recommendation is driven by your water chemistry, not a manufacturer's margin.
Honest about precision
Where product concentration matters — like muriatic acid or chlorine — we defer to your label. No invented universal number that could harm you.
Nothing to install
Works right from your phone browser, poolside. No app store, no account, no download — open it and go.
Reminders
A nudge before a parameter drifts out of range.
Our Philosophy
Why we don't guess.
When a number controls a dose, we'd rather hand you the safe decision than a confident-sounding wrong one.
Every pool calculator you've tried probably has a dropdown for “chlorine type” or a single multiplier for muriatic acid. The math looks tidy. The problem is that real products are anything but standard — a gallon of one brand of liquid chlorine can carry 6% available chlorine while another carries 12.75%, and muriatic acid typically ranges from 15% to 31.45%. A dose calculated against the wrong concentration either wastes the chemical, fights you to zero effect, or — worse — pushes the pool past where it should sit.
ClearDose handles the parts of water chemistry where precision is safe: ranges, expected deltas, the right order of operations, and how one adjustment interacts with the next. For acid and chlorine specifically — the two steps where concentration governs the dose — we don't invent a single universal number. We tell you what to do, and we point you at your product label for the figure that decides how much. The label is the source of truth for what's actually in the jug in your hand.
Following the label isn't a hedge. It's the safety floor. Wrong calculations can etch plaster, throw a Saturday morning of work into the drain, leave you with green water from depressed chlorine, or — at the bad end — put swimmers in water that isn't ready. We'd rather tell you the honest thing (“check your label”) than hand you a confident number that sends you the wrong way. Every recommendation on this site is built to be safe even if you only do half of what we suggest.
You'll find the same principle restated under every sample analysis in our safety note, and in the dose-by-label guidance that follows your readings. We're not the source of truth on your product — your manufacturer is. We're the second opinion that knows the rules and won't bluff past them.
