How does pHin work if I don’t have an active subscription?


The pHin monitor and mobile app continue to monitor your water without an active subscription. You’ll be able to check the temperature of your water at any time. Instead of receiving chemical recommendations pHin will let you see if your pH and sanitizer levels are ‘Okay’ or ‘Not Okay’.

You can purchase a pHin monitoring subscription at any time to receive the following features:

  • Push notifications to alert you of water adjustments: pH, sanitizer, and more
  • Scan your chemicals to receive dosing instructions
  • Water history charts up to 90 days
  • pHin test strips to monitor your TA, TH, and CYA

You must maintain an active monitoring or chemical subscription to receive a free monitor replacement in the event that the monitor is faulty or the battery dies.
