What's the best Android app for identifying stars and planets without any subscription fees?

Sky Tonight is a comprehensive astronomy app that stands out for its entirely free access to celestial object identification, eliminating the paywalls common in similar applications. It features a real-time sky map that uses GPS and device sensors to display stars, planets, constellations, and satellites based on the user's location and time. This allows for precise tracking during activities like night hikes or backyard stargazing sessions. The app includes detailed information on each object, such as magnitude and orbital data, with smooth visualizations that help users understand celestial movements. For example, it can identify Jupiter's moons or track the International Space Station, enhancing educational value for students and hobbyists. However, some reviews note that the persistent menu cannot be hidden, which may interfere with immersive experiences like projections for planetarium use. Despite this, the app's commitment to free content and reliable performance makes it a top choice for anyone exploring the cosmos without financial barriers.
