About this app
Pool Water is a pool chemistry calculator for pool service professionals. It turns your test readings into exact chemical amounts.
Enter what you measured — chlorine, pH, alkalinity, stabilizer, calcium — and
get back how much of what to add, in the order to add it. No conversion tables,
no mental math on the side of a pool in 110-degree heat.
BUILT FOR ROUTES, NOT FOR ONE BACKYARD
Keep every pool you service in one list. Volume and chlorine type are saved per
pool, so you pick the pool and start entering numbers. Every test you run is
kept, so you can see what the water did last week before you decide what to do
today.
8 LANGUAGES - SPANISH, TAGALOG, VIETNAMESE, CHINESE, KOREAN AND MORE
English, Spanish, Tagalog, Chinese, Vietnamese, Korean, Amharic, and Afaan
Oromoo. Switch any time — it takes one tap, and it changes the whole app, not
just the menus.
DOSING YOU CAN CHECK
The amounts come from published industry standards: PHTA/APSP-11 water balance,
the Trouble Free Pool chlorine-to-stabilizer ratios, and National Swimming Pool
Foundation dosing tables. The app tells you the target range it is aiming for,
so you can see why it is asking for what it is asking for.
It also catches the mistakes that cost money. Low pH does not mean "add acid" —
the app says so, and says what to do instead.
PRICING THAT DOES NOT CHANGE ON YOU
Free: three calculations a day. Saving pools and readings is unlimited and
always free — your records are yours, and they are never held hostage.
Unlock: $10, once, forever. Not a subscription. Unlimited calculations, and
results that update live as you type instead of waiting for a button.
NO ACCOUNT, NO TRACKING
There is nothing to sign up for. Your pools and readings stay on your phone.
The app has no analytics, no ads, and no trackers.
Dosing guidance is provided for informational purposes. Always follow the
instructions on your chemical containers and your local health code.
