Your thermostat only tells part of the story. Sticky or Dry brings temperature and relative humidity together, helping you understand how the air in and around your home actually feels. Compare indoor and outdoor conditions, see how they change over time, and get practical guidance for making your place feel better. KNOW WHAT TO DO NEXT The Indoor Climate Guide compares your chosen indoor and outdoor data points and considers the climate-control equipment available in your home. It can help you decide when to open or close the windows, use an air conditioner or heater, adjust window shades, or simply turn on a fan. When enabled, it can also look at the next six hours of weather to prepare for changing conditions. COMFORT IS MORE THAN TEMPERATURE Two rooms at the same temperature can feel completely different. The reason is moisture. Relative humidity describes how much moisture the air holds compared with the maximum it could hold at that temperature. Dew point brings temperature and relative humidity together into a clearer measure of how much moisture is actually in the air. A lower dew point tends to feel dry. A higher dew point can feel sticky or muggy. Sticky or Dry visualizes this relationship using colored comfort bands, helping you see at a glance where each room or location sits. BRING YOUR CONDITIONS TOGETHER Add different kinds of data points to the same interactive chart: • Weather locations with current outdoor conditions and forecast • Compatible temperature and humidity sensors from the Apple Home app • Manual data points you can drag around the chart yourself Manual data points make the app useful even without a home sensor. Use them to enter a reading from another thermometer or hygrometer, or explore how different combinations of temperature and humidity might feel. Compatible Apple Home accessories include sensors such as the SONOFF AirGuard, Aqara Climate Sensor W100, Eve Weather, IKEA ALPSTUGA, and IKEA TIMMERFLOTTE. Compatibility depends on the accessory exposing its temperature or humidity readings through the Apple Home app. SEE HOW CONDITIONS CHANGE Historic trails show how each data point has moved across the chart over time. Follow up to 24 hours of captured readings to see whether a room is becoming warmer, cooler, drier, or more humid. MAKE IT YOUR OWN • Give every data point its own label and color • Choose Celsius or Fahrenheit • Set your desired indoor temperature range • Select the equipment available in your home • Compare any indoor and outdoor data points • Inspect temperature, relative humidity, and calculated dew point at a glance Sticky or Dry is designed for iPhone, iPad, and Mac. Its comfort calculations and guidance are performed on-device. Understand your indoor climate and make your place feel better.
