About this app

Works with ANY brand of pool test strip. StripWise reads your strip from a photo, logs your water chemistry, and tells you exactly how much of YOUR own chemicals to add — and the manual log, the dosing calculator, and CSV export are free forever.

Most pool scanners only read that one brand's strips, then paywall the basics. StripWise is the brand-neutral, honest alternative for pool and spa owners who just want to keep their water balanced.

WORKS WITH ANY TEST STRIP
• AI-assisted strip reading that works with strips from all the major brands — you are never locked to one company's strips.
• Guided capture (flash on, strip flat on its own color chart) for a cleaner read.
• You review and confirm every value before anything is saved — and when the AI can't read a pad reliably, it says so and leaves it blank for you to enter by eye, instead of guessing. Honest beats magic.
• Prefer not to scan? Manual entry is always one tap away and always free.

DOSING CALCULATOR IN YOUR OWN CHEMICALS
• Tells you how much to add in the exact products and units you actually use — liquid chlorine (6 / 10 / 12.5%), cal-hypo, dichlor, muriatic acid, soda ash, baking soda, calcium chloride, cyanuric acid, and pool salt.
• Water-balance chemistry done right: the free-chlorine / stabilizer relationship, pH and alkalinity, and the saturation index that tells you if your water is corrosive, balanced, or scaling.
• Dosing output is informational — you confirm the amount and add your own product, following its label.

LOG EVERYTHING — FREE, FOREVER
• Unlimited manual readings, the full dosing calculator, and CSV export are free forever. Your history is never held hostage by a lapsed subscription.
• Server-backed and reliable — your log doesn't vanish.
• Date-grouped history, in-range / low / high status on every reading, and trend charts with your target bands shaded in.

BUILT FOR POOLS AND SPAS
• Multiple pools and hot tubs / spas as first-class types — the year-round hedge for spa owners and the busy season for Sunbelt pools (FL, TX, AZ, CA).
• Saltwater and salt-water-generator (SWG) support.
• Chlorine, bromine, and salt strips all covered.

FREE, AND FAIR
• Free forever: unlimited manual logging, the dosing calculator, CSV export, trends, and 3 AI strip scans every month, for 1 pool or spa.
• StripWise Pro ($21.99/year with a 14-day free trial, or $49.99 once for lifetime): unlimited AI scans, unlimited pools and spas, and trend insights.
• The paywall sells more scans and more pools — never the basics. Logging, dosing, and exporting your data stay free.

StripWise is a water-chemistry record-keeping and calculation tool. It balances your water, not people — it gives no medical or swimmer-safety advice. Always handle, store, and add pool chemicals per the manufacturer's instructions.
