Most solutions measure just one thing — like moisture or sunlight — and give you a number without any context, leaving you guessing on what to do next. Willow knows your specific plant, understands its environment, and factors in things like location, seasonality, and weather. Then it turns all the complexities of plant care into simple, timely alerts that tell you exactly when and how to care for your plant.

Our Sensor is intended for indoor use with houseplants only. The great outdoors can feature heavy rains or snow, prolonged harsh sunlight, or extreme temperature changes compared to the relatively controlled indoor environment. The tech inside the Sensor is safeguarded well for indoors but risks getting damaged in an outdoor setting.

For the best Willow experience, use one Sensor per plant at a time. Your Sensor is paired up per your plant’s type in the app during setup so it can monitor your plant’s species-specific preferences. In the event your original plant is thriving and you’re feeling confident to switch the Sensor to another plant, you can easily move it! Just unpair it from the first plant in the app and pair it up with the new one.
