Astrolapp Live Sky Map

Astrolapp is a mobile application that allows users to observe and identify planets, stars, and constellations by holding their device up to the sky. The app features a highly sensitive and accurate Live Mode, which is only available on devices with a built-in compass. The Live Mode provides a visually appealing and intuitive interface for users to explore the night sky.

The stars in Astrolapp are drawn with their true colors and labeled with their names according to the International Astronomical Union. Users also have the option to view the 88 official constellations with or without name labels. The app also offers a powerful search function and an arrow guide to help users locate any celestial body above their head.

By tapping on a star or planet, Astrolapp highlights its path across the sky throughout the night or day. The app also calculates the rise and set times for each celestial body and displays the current position data in a separate tabular form. Astrolapp automatically detects the user's location and uses it to accurately depict the starry sky. However, users can also use the built-in map to select any other location and view the sky from there.

In addition to the Live Mode, Astrolapp also offers a star-map-mode for devices without a built-in compass. This mode features an interactive star map in the style of an astronomical clock, which visualizes the mechanics of the Solar System and the movements of the stars and constellations throughout the day and year. The app also allows users to view the sky in fast motion, making it easy to see changes over time.

Astrolapp also offers a range of features, including a quiet night sky with no sounds or advertisements, accurate live mode with Kalman filter technology, and the positions of the Sun, Moon, and planets. Users can also view the 9096 brightest stars and the 88 constellations of the IAU, as well as rise, set, and transit times for all celestial objects. The app also provides numerical position data in various coordinate systems and allows users to manually select and save their location on a map. With its various features and modes, Astrolapp is a comprehensive and user-friendly tool for exploring and learning about the night sky.
