Never run outside to save
your laundry from rain
again.

Stop checking the weather app every hour. DryCast uses local meteorological data to give you a precise drying score and proactive rain alerts.
How it Works
For the curious: the science behind the score.
The Drying Core™ Algorithm
Standard weather apps tell you if it's "sunny." We tell you if it's "drying."
Our engine pulls real-time data from Apple Weather (WeatherKit) and Open-Meteo, processing 4 key variables:
- 01.Vapor Pressure Deficit: We calculate the difference between air moisture and saturation. High VPD = Fast drying.
- 02.Wind Desiccation: Wind speed significantly accelerates evaporation by removing the boundary layer of moisture.
- 03.Solar Irradiance: Direct sun exposure provides the energy for phase change from liquid to vapor.
- 04.Dew Point Prediction: We monitor the delta between air temp and dew point to predict condensation risk.
Smart Laundry Weather
Everything you need to time your laundry perfectly.
Instant Rain Alerts
Never let your fresh laundry get soaked again. We notify you before the rain starts so you can save your clothes in time. Optimized for low-latency delivery.
Precision Drying Score
We calculate a 0-100 score based on vapor pressure, wind speed, and solar radiation so you know exactly how fast clothes will dry.
Best Drying Window
We tell you the exact hours when drying conditions are best, so you don't waste time. Maximize your outdoor drying efficiency.
Fabric Sensitivity
Jeans dry slower than t-shirts. Our algorithm adjusts the drying time predictions based on the fabric density you're washing.
Indoor Mode
Drying inside? Switch to Indoor Mode to prioritize humidity and air circulation over wind and sun exposure.
Home Widgets
See the drying score at a glance right from your home screen. Native iOS and Android widgets supported.
Built out of frustration.
I live in a place where the weather changes in minutes. Like many of you, I've had to sprint outside to save a load of fresh laundry from a sudden downpour more times than I care to admit.
Standard weather apps are great for knowing if you need an umbrella, but they're terrible at predicting if your jeans will actually dry by 5 PM.
I built DryCast to solve my own problem. I wanted an app that understood drying conditions, not just weather. After weeks of testing algorithms and atmospheric data, I'm excited to share it with the Hacker News community.
