Water log
Your pool readings, timestamped & on this device.
Log every test kit result — pH, free and total chlorine, total alkalinity, calcium hardness, cyanuric acid, salt — then watch the trend over the season. Everything lives in this browser's storage; clearing your site data wipes the log along with it. No account, no sync.
