Rain? answers one simple question: how likely is it to rain in the next 30 minutes? Open the app and instantly see your rain probability as a single, bold number. The screen fills with animated water proportional to the chance of rain — the higher the likelihood, the higher the water rises. Inspired by the Apple Watch depth gauge, it turns weather data into something you can feel at a glance. Beneath the headline number, a minute-by-minute chart breaks down the next half hour so you can see exactly when rain is expected to arrive, peak, or clear. A trend indicator shows whether conditions are building, easing, or holding steady. No clutter. No ten-day forecasts. No hourly temperature graphs. Just the one thing you actually need to know before you step outside. How it works: Rain? uses Apple WeatherKit to pull minute-by-minute precipitation data for your exact location. Your location is sent directly to Apple's weather service and is never stored, tracked, or shared. The forecast updates with a single tap. Features: Real-time rain probability for the next 30 minutes Animated water-fill display that rises with rain likelihood Minute-by-minute precipitation chart Trend indicator showing increasing, decreasing, or steady conditions Hyperlocal forecasts powered by Apple WeatherKit No ads, no accounts, no tracking Designed for one-handed, one-second use Rain? requires location access to provide forecasts.
