## Description

Test your water, type in the numbers, and get an answer you can actually hold: add 9.6 fl oz of muriatic acid. Not a color chart, not a lecture - an amount, sized to your exact pool.

Set up your pool or hot tub once with its real volume. From then on, every dose is computed for YOUR water, not a 10,000-gallon example on the back of a bottle.

WHAT IT DOES

- Log the readings your test kit gives you - free chlorine, pH, alkalinity, calcium hardness, stabilizer, salt. Skip what you didn't measure.
- See where each number sits against the right range for your setup. Chlorine targets follow your stabilizer level, the way pool chemistry actually works.
- Get chemical amounts in units you can measure out: fluid ounces, pounds and ounces, teaspoon-scale grams for hot tubs.
- pH doses come with the honest caveat - they're estimates, capped at a safe single dose, with a retest reminder built into the advice.
- Test reminders that count from your last logged test, not an arbitrary calendar. Miss a week and it nudges you tomorrow morning, not three cycles from now.
- Import your history from a CSV file - exports from other pool apps and spreadsheets work. Export everything back out anytime. Your log is a file you own.

HOT TUBS ARE NOT SMALL POOLS

A 350-gallon spa gets spoon-sized doses, its own target ranges, and stabilized-granule math. If you've been told your tub is too small to be supported, you're exactly who this app was built for.

NO SUBSCRIPTION. NO ACCOUNT. NO CLOUD.

Everything stays on your phone. No login, no sync service holding your data hostage, no monthly fee to keep your own test history. The privacy label reads "Data Not Collected" because there is nothing to collect.

ONE THING TO KNOW

Dosing here is guidance, not gospel: add, circulate 30 minutes, retest. Always follow the product label - it wins over any app. Never mix chemicals with each other.
