FrostClock

FrostClock is a mobile + web app that predicts first/last frost windows for a precise location and tracks how those dates shift year over year. It combines public weather station data with hyperlocal interpolation and optional user-submitted thermometer readings to improve accuracy at the neighborhood level. Users get a simple “plant-safe window” calendar, alerts when conditions trend toward an early frost, and a season summary showing how unusual the year was versus the last 10–30 years. It’s built for people who make real decisions around seasonal patterns—when to plant, protect, or harvest—without forcing them to interpret meteorology charts. This is not a general weather app; it’s a focused seasonal-pattern tool with clear, actionable outputs. Monetization is straightforward: a free tier for basic frost windows and a paid tier for higher-resolution forecasts, historical exports, and multi-location tracking.
