About this app

Clearly turns your water test into a simple plan: what to add, how much, and in what order. For pools and hot tubs, with any brand of chemicals.

GREEN OR CLOUDY WATER? TAKE A PHOTO
Photograph the water and Clearly suggests likely causes and safe next steps in plain language. It's optional, needs no account, and your photo is not stored.

NO ACCOUNT. WORKS OFFLINE.
Open the app and test. Your data stays on your phone. No sign-up, no login problems at the pool store, no tracking. (Photo diagnosis needs a connection.)

ANY BRAND, NO SALES PITCH
Clearly doesn't sell chemicals, so it never pushes products. Pick what you actually use: liquid chlorine (6%, 8.25%, 10%, 12.5%), cal-hypo or dichlor; muriatic or dry acid; calcium chloride flakes or pellets.

A STEP-BY-STEP PLAN
• Exact amounts in gallons, ounces and pounds, or liters, grams and kilograms
• The right order: shock first, then alkalinity, pH, calcium, stabilizer, chlorine last
• How long to wait, when to retest, and when you can swim again
• Check off each step as you go

"WHAT IF I ADD...?"
Added a different amount than the plan said? Enter it and see what it does to chlorine, stabilizer, calcium, alkalinity, salt and pH.

TARGETS THAT MAKE SENSE
• Free chlorine target based on your stabilizer (CYA) level
• Ranges for plaster, vinyl and fiberglass pools, salt water pools and hot tubs
• pH dosing that accounts for your alkalinity
• Water balance (CSI), plus optional phosphate and borate readings

TEST STRIPS OR DROP KITS
Type the numbers from any drop kit, or tap the color that matches each pad on your strip. Calcium, stabilizer and salt carry over from your last test, so a quick chlorine and pH check takes seconds. Forgot to log a test? Enter it with its real date.

HOT TUBS TOO
Chlorine or bromine, with hot-tub ranges and reminders to drain and refill.

HISTORY, UPKEEP AND REMINDERS
• Trend charts with your target range
• Every test saved with its plan, and a backup you can copy to a new phone
• Upkeep schedule, opening and closing checklists, and a shopping list
• "Time to test" reminders every 1-7 days

Clearly is in early access and every feature is free right now. Tell us what's missing from Settings > Send feedback.

Photo diagnosis is guidance, not a lab test: a photo can't confirm your water chemistry, so always test the water. Always follow product labels. Amounts are estimates; if unsure, ask a pool professional.

What’s new

Clearly now speaks German (Settings > Language). Dates in French and German now use the local day-month order.
