This astronomy application has an easy to use and minimalist user interface, that makes it one of the best astronomical applications for adults and children who want to explore the night sky. Stellarium Mobile features: • View an accurate night sky simulation of stars and planets for any date, time and location. • Dive in a collection of many stars, nebulas, galaxies, star clusters and other deep sky objects. • Zoom on realistic Milky Way and Deep Sky Objects images. • Discover how people living in other regions of the planet see the stars by selecting the shapes and illustrations of the constellations for many sky cultures. • Track artificial satellites, including the International Space Station. • Simulate landscape and atmosphere with realistic sunrise, sunset and atmosphere refraction. • Discover 3D rendering of the major solar system planets and their satellites. • Observe the sky in night mode (red) to preserve your eyes adaptation to darkness. Stellarium Mobile contains in-app purchases allowing to upgrade to Stellarium Plus.

Verdict
The clearest difference is review sentiment: Stellarium Mobile at 84% against DJI Simulator's 24%. Stellarium Mobile also leads on rating (4.8 vs 2.4) and ratings volume (37K vs 43). DJI Simulator's advantage is in-app purchases (none vs 2) and iOS requirement (13.0 vs 17). On price, update cadence, ads and device support there is nothing between them.
