ClearPool helps you keep a private, structured record of pool care. Log a water test, compare each reading with the target range you set, and keep maintenance from slipping.

People who used an earlier version keep their existing allowance of ten free tests. Existing records remain visible and editable. Backup, restore, and Delete All Data remain free. Pro adds unlimited new tests, continued product-label scaling, the full trend and balance detail, PDF and CSV exports, and CSV import. INFORMATIONAL, ON PURPOSE ClearPool does not calculate a chemical treatment, target, product strength, frequency, or maximum amount. It scales one amount copied from a product label solely by the pool-volume ratio. Read and follow the complete manufacturer label for how much and how often to apply, protective equipment, circulation, retesting, and swimming. Never mix pool chemicals. Consult a qualified pool professional when needed. PRIVATE BY DESIGN Pool records are stored locally on your device. ClearPool has no account, advertising, analytics, or tracking. The support form sends the fields you enter plus the app, version, build, and device details shown before you tap Send. Exports and backups leave the app only when you select a destination. PURCHASE DETAILS ClearPool Pro offers subscription and lifetime purchase options. The App Store shows the options available in your region before confirmation. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically until cancelled. Manage or cancel in Settings > Apple Account > Subscriptions. Cancellation takes effect at the end of the current period.
