Thank you for being a part of my journey with Luminos! As I strive to bring you the best in astronomical software, I want to let you know that, after 12 years of updates, this version of Luminos will be retired in 2023. But there's exciting news: I've developed Luminos Pro, an advanced version that offers even more amazing features and updates. To continue providing support and updates to my existing customers, this version will stay available in the App Store for now. I invite you to explore my latest features and designs in Luminos Pro and join me on this continuing adventure. See you in the stars! Clear skies, - John

Journey across the entire observable universe — from the Moon to the relic light at the edge of all we can see. Space is an interactive 3-D atlas of the cosmos. Every object is placed in its true position in the sky and at its real distance, on a scale that lets the Moon and the cosmic horizon share one navigable space. Tap anything to discover how far back in time you are seeing it — because the further away an object is, the older the light reaching your eyes. EXPLORE IN 3-D Drag to orbit, pinch to zoom, and tap any object to inspect it up close. Glide past planets, stars, nebulae, galaxies, black holes and quasars rendered from real NASA and ESO imagery. LOOK BACK IN TIME Light takes time to travel. Each object reveals its light-travel time from Earth — see the Sun as it was 8 minutes ago, Andromeda 2.5 million years ago, and the cosmic dawn 13.8 billion years ago. A LIVING SOLAR SYSTEM Watch the planets orbit on real elliptical paths, with moons, asteroid and Kuiper belts, and comets streaming twin tails. 130+ CURATED WONDERS A hand-built catalogue spanning planets, famous stars, exoplanets, nebulae, galaxies, galaxy clusters, neutron stars, black holes, quasars and the cosmic web — each with facts, properties and distances verified against NASA, ESA and Gaia data. LIVE FROM NASA The nearest confirmed exoplanets stream in live from the NASA Exoplanet Archive, slotting into their true positions in the sky. JOURNEY THROUGH TIME Sit back for a guided tour outward from the Moon to the beginning of time, narrated by the light of each milestone along the way. LAUNCH FROM EARTH Choose a destination and ride a spacecraft there on a real gravity-turn launch — lift off, accelerate, cruise and arrive. FULLY BILINGUAL Complete English and Arabic support, with right-to-left layout. Switch languages anytime. Download Space and hold the universe in your hands.

Verdict
The clearest difference is price: Cosmo Pro at Free against Luminos's $19.99. Luminos's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 3 months). On ads and device support there is nothing between them.
