Exoplanets are planets orbiting stars beyond our own solar system. This app allows you to explore all discovered exoplanets, their measured physical properties, their location in the night sky, and their host stars. An interactive model shows you the entire observable universe, all the way from the surface of the Earth to the cosmic microwave background. This app has been developed by a professional astronomer. Main features: * Interactive visualizations and animations. * Physical properties of all detected exoplanets and their host stars, updated on a daily basis. * Stunning 3D model of our Milky Way showing the location of all known exoplanets. You can zoom into any planetary system, explore how the night sky and the constellations look from the surface of other planets, or zoom out and see other local galaxies and galaxy clusters as well as the cosmic microwave background. * Visualizations of exoplanet orbits and the habitable zone. * Choose between the Open Exoplanet Catalogue, the NASA Exoplanet Archive, and the Extrasolar Planet Encyclopedia (exoplanet.eu). * Push notifications are sent out whenever a new planet is discovered. * Augmented reality sky map: point the phone towards the sky to find an exoplanet! * Interactive multi-touch correlation plots. * Solar System planets, major moons, and asteroids are included. * Explore S-Stars orbiting the black hole at the Galactic Center of our Milky Way * Background information about exoplanets and detection methods. * Full support of planets in binary, triple, quadruple systems and orphan planets. * Real-time ray tracing on the GPU.

This app invites you to explore the relative motions of our solar system's planets, their moons, and several exoplanet systems. It is based on ideas presented in "A Little Book of Coincidence" by John Martineau. Are the amazing patterns created by these orbiting bodies just a coincidence, or is something more than that going on? Take a look and see what you think. Be sure to check out the special relationship between the Earth and Venus.

Verdict
The clearest difference is rating: Exoplanet at 4.7 against Celestial Dances's 3.0. Exoplanet also leads on update cadence (every 2 weeks vs every 30 months) and ratings volume (956 vs 2). Celestial Dances's advantage is in-app purchases (none vs 7) and review sentiment (100% vs 91%). On price and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Exoplanet sells 7 one-off in-app purchases. Celestial Dances asks for nothing beyond the download.
Exoplanet holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Exoplanet has 956 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 91% of Exoplanet's written reviews are positive against 100% of Celestial Dances's, so the app with the better star average is not the one people write more warmly about.
Exoplanet ships an update every 2 weeks, Celestial Dances every 30 months. The most recent releases landed on October 11, 2026 and October 3, 2026 respectively.
