About

PoolKeep

Features
Read full description

Stop guessing how much chlorine, acid, or baking soda your pool actually needs. PoolKeep turns your test strip readings into an exact treatment plan — the specific chemical, the exact amount for your pool's size, and the order to add it in, so you're never second-guessing a dose again. WHAT POOLKEEP DOES • Log your test results (pH, chlorine, alkalinity, CYA, hardness, salt) in seconds • Get a health score and a clear "in range / monitor / action needed" read on every parameter • Follow a step-by-step treatment plan with exact chemical amounts sized to your pool • Track trends over time with charts for every parameter, so you catch problems before they're a problem • Scan your test strip with your camera to help read the colors — you always confirm the numbers yourself • Get reminders so testing becomes a habit, not an afterthought • Share your pool's history with a pool pro or family member in one tap WHO IT'S FOR Anyone with a pool — chlorine or saltwater — who's tired of guesswork, conflicting advice, or trips to the pool store just to find out what to add. Whether you're brand new to pool care or you've been doing it for years, PoolKeep gives you a straight answer every time you test. Your pool, dialed in — no guesswork required.
