Astronomical Skills is an Android education app from Celestial Education Labs, designed to help users learn astronomy through interactive calculations, observation tools, and navigation challenges. It combines a real-time celestial mechanics engine with a star-mapping simulator covering more than 8,000 stars and 150 deep-sky objects. Using a device’s GPS and gyroscope, its augmented reality sky map helps identify stars, planets, constellations, and satellites.

The app’s toolkit includes an orbital mechanics calculator based on Kepler’s equations, a spectroscopy training lab, and lessons in celestial navigation. Users can explore a catalog of more than 2,500 Messier, NGC, and IC objects, track constellations, and view predictions for eclipses, transits, occultations, and planetary conjunctions. Additional learning features cover coordinate systems, parallax, atmospheric refraction, and stellar spectra. Astronomical Skills is listed as version 3.2.1 for Android 8.0 and above, with a 10+ age rating. It can be started without an account, and optional in-app purchases provide access to premium observation modules.
