PoolDose: Salt Pool Calculator

PoolDose is a salt water pool calculator and chemical dosing app for the person who owns the water, not a lab. Point your camera at a test strip and PoolDose turns the reading into the exact amount to add — in cups, ounces and pounds, sized to your gallons and to the product already sitting in your garage.

No ads. Not one.

▶ SCAN THE TEST STRIP
✓ Reads standard 6-in-1 and 7-in-1 test strips with your camera
✓ Any brand of strip — you are not locked to one manufacturer's box
✓ Total chlorine, free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid and salt
✓ A confidence score on every pad, so you can fix a misread before it reaches the math
✓ Manual entry any time you would rather type the numbers yourself

▶ SALT WATER POOL CALCULATOR
✓ Enter your salinity reading and get the pounds of salt to add
✓ Sized to the target range your salt water chlorine generator wants to see
✓ Salt, liquid chlorine or tabs — the same calculator covers every setup
✓ Tells you the amount, not a vague "add a couple of bags"

▶ THE EXACT DOSE, NOT A RANGE
✓ Liquid chlorine 12.5%, chlorine tabs, cal-hypo 65%, dichlor 56%
✓ Soda ash to raise pH, muriatic acid to bring it back down
✓ Baking soda for total alkalinity
✓ Calcium chloride for calcium hardness
✓ Stabilizer (cyanuric acid) when the sun is eating your chlorine
✓ Every amount rounded to a fraction you can actually measure out

▶ COMBINED CHLORINE, WORKED OUT FOR YOU
✓ Combined chlorine derived from your free and total readings
✓ Watch chloramine climb before anyone complains about the smell
✓ Free chlorine at zero and the water going cloudy? You get the amount that brings it back to target, in one number

▶ IN THE RIGHT ORDER
✓ Doses sequenced, with the wait time between them
✓ When nothing can bring a level down, PoolDose tells you how much water to swap instead

▶ HISTORY AND TRENDS
✓ Every reading kept and charted across the whole season
✓ Drift detection surfaces the value that keeps sliding week after week
✓ Fix the cause once instead of re-dosing the same thing every Saturday

▶ SEASONAL PROGRAMS
✓ Spring open checklist, in the order the chemistry actually wants
✓ Winter close checklist, so nothing is forgotten in October

▶ WHAT IT COSTS
✓ An approximate chemical cost estimate for every dose
✓ See what a treatment runs before you pour it

▶ BUILT FOR THE DECK, NOT THE DESK
✓ Readings save offline and sync later — equipment pads rarely have a bar
✓ Push reminders so a test does not quietly slip a week
✓ Sign in with Apple
✓ English, German, Spanish, French, Italian and Lithuanian

▶ FREE AND PREMIUM
Free: one body of water, your last 7 readings, and 3 test strip scans.
Premium: unlimited pools and spas, unlimited history, and up to 20 photo scans a day.

WHO THIS IS FOR
Homeowners with an inground or above-ground pool, a salt system, or a hot tub, who are tired of guessing. If you have ever stood over a bucket wondering whether that was two cups or three, this is the app.

PoolDose does the chemistry math. It does not replace the dosing and safety instructions printed on your chemicals — always read the label, never mix products in the same container, and always add product to water rather than water to product.
