Turn pool-test numbers into exact chemical amounts in seconds. Unlimited local history, no account, and one lifetime unlock — never a subscription.
Test your pool water, enter the readings, and get a clear plan with exact chemical amounts. PoolSolve is a private, offline-first pool calculator and water log for owners who maintain their own pool or spa.
FROM TEST KIT TO WATER PLAN
• Enter only the readings you have
• See which readings are low, high, or on target
• Get chemical recommendations in a safe order
• See amounts in gallons, ounces, pounds, liters, milliliters, or grams
• Record what you added with one tap
POOL CHEMISTRY WITHOUT THE GUESSWORK
PoolSolve supports free chlorine, combined chlorine, pH, total alkalinity, calcium hardness, cyanuric acid (stabilizer), salt, bromine, water temperature, and the calcite saturation index (CSI). Choose the product you actually use, including liquid chlorine, bleach, cal-hypo, dichlor, trichlor, muriatic acid, dry acid, baking soda, calcium chloride, stabilizer, and pool salt.
MADE FOR YOUR POOL
• Chlorine, saltwater, and bromine pools or spas
• US and metric units
• Built-in volume estimator for rectangular, oval, and round pools
• TFP-style or industry target ranges
• Fully editable minimum, target, and maximum values
PRIVATE BY DESIGN
No account, sign-up, email, or cloud sync is required. Your pool readings and chemical history stay on your device. The core workflow works offline. Export your history to CSV, create a portable data backup, or share a formatted PDF when you choose.
UNLIMITED HISTORY IS FREE
The calculator, one pool, and unlimited test and chemical-addition history are free. PoolSolve does not limit you to a trial log or require a subscription for the core workflow.
ONE LIFETIME UNLOCK — NO SUBSCRIPTION
A single non-consumable purchase unlocks:
• Multiple pools and spas
• Trend charts with target bands
• Maintenance reminders
• Formatted PDF water reports
Buy once through the App Store and restore the purchase on another compatible device using the same store account.
PoolSolve gives DIY pool owners a faster path from test result to confident action, without ads, forced accounts, or recurring fees.
