Bridging the gap between nature and technology.
Plants communicate through their environment—but understanding what they need isn’t always easy. That’s where OKO comes in.
The OKO Smart Sensor measures the key factors that affect your plant’s health: soil moisture, temperature, pH, and air humidity. It takes the guesswork out of plant care by delivering real-time insights directly to your phone through the OKO App.
The app keeps you connected to your plants. It translates sensor data into simple, actionable tips—so you’ll know when to water, adjust room temperature, or make other changes to keep your plants thriving.
With OKO’s smart technology, plant care becomes second nature. We make it easy for anyone to create a greener, healthier home—no green thumb required.
