Sunlitt is a solar trajectory and sunshine analysis tool designed for photography.

Architecture, real estate, and outdoor exploration. It can calculate key times in real time based on current location, including sun position, azimuthal, altitude, sunrise and sunset, golden hour, blues hour, and summer and winter solstice, and visually present changes in sunlight and shadow on maps and scenes. It supports offline viewing of basic data, and with AR mode, previews the sun’s path and shadow movement in real environments. It also allows observation of hills and buildings on light through shadow maps, terrain shadows, and satellite or terrain views. The app is compatible with iPhone, iPad, Mac, Apple Watch, and Vision Pro, offering widgets, real-time activities, shortcuts, and multi-device sync, making it easy to quickly access reliable references when choosing shooting locations, choosing seats to avoid sunlight, scheduling, and preparing for outdoor activities.
