# Coffee in the Sun

> Coffee in the Sun is an iOS app that shows real-time building shadows on a live map, helping users find sunny terraces, cafes, and restaurants. It uses real building geometry combined with precise solar position calculations to accurately simulate where the sun is shining and where the shade falls, at any location and any time.

The app is designed for anyone who wants to enjoy their coffee, lunch, or drinks in the sun. It answers the simple question: "Which terrace has sun right now?" — and also: "Which terrace will have sun at 2 PM next Saturday?"

Coffee in the Sun is available on the Apple App Store (iOS). It supports 34 languages and works worldwide.
