PoolLog is the field journal for your pool. Log water tests, get precise chemical dose calculations, and track how your water changes over the season — without a subscription.

Test Results In. Doses Out. Enter your test strip readings and PoolLog instantly calculates the exact amount of every chemical you need — chlorine, pH adjuster, alkalinity increaser, calcium hardness, stabilizer, and salt. Doses are calculated for your specific pool volume so the math is always right.

A Season Log Built for Homeowners Every reading you record is saved to your history. See how pH and free chlorine trend over 30 days, spot drift before it becomes a problem, and build a complete picture of your water over the entire season.
