ChillCast tracks chill hours for fruit trees using historical weather data. On first launch, set your location using the location button or by entering coordinates manually.
Chill hours measure the amount of cold exposure fruit trees receive during winter dormancy. Most deciduous fruit trees need a minimum number of chill hours to produce fruit properly.
ChillCast supports three models: 45°F Hours (traditional, counts hours between 0-7.2°C), Utah (weighted by temperature band), and Dynamic (Fishman-Erez, best for mild climates).
Weather data comes from NASA POWER. ChillCast uses regional hourly temperature estimates and displays the latest available data date in the app. NASA does not endorse ChillCast.
