About pHin

pHin is reinventing pool and hot tub care with a WiFi-enabled smart monitor and a mobile phone app to take away the guesswork. The pHin Smart Monitor continuously monitors your pool or hot tub water chemistry and temperature, and notifies your phone when you need to balance the water quality. All you need to do is add pHin’s pre-measured, single-dose, color-coded pods or get dosing instructions to use it with your own chemicals. One-touch pool service is also available through our network of pre-qualified pool technicians whenever needed at a pre-negotiated price.

pHin is the first product from ConnectedYard Inc. headquartered in San Jose, California, which is dedicated to being the center of the connected backyard. Beginning with pool and hot tub care, our smart technology will expand to include everyday components involved in outdoor living. Our goal is to bring intelligence, simplicity and fun to the backyard.
