Continuous Water Monitoring is
More Effective and Reliable
pHin monitors your water 24/7 and tests it 144x per day. That’s over 1,000 times more than usual!
Our algorithm interprets the results to give you better water quality readings so that you add the right amount of chemicals to your pool or hot tub.
Your Water Quality at a Glance
Knowing your pool is healthy shouldn't require a chemistry degree.
The pHin App uses a simple color-changing disc to indicate your water quality.
Automatic App Notifications
Relax and enjoy your water.
pHin will alert you when you need to adjust your chemicals and let you know exactly how much of which chemical to use.
Takes the Guesswork Out of Your Chemicals
Scan any supported chemical’s barcode and the pHin app will calculate exactly how much to add to your water.
You never need to worry about overchlorinated or out of balance water again.
