DeepSpace turns your device into a personal star atlas — no account, no subscription, no internet required. What's in the sky tonight? Hold up your phone and explore 95 named stars rendered in color by spectral type, all 8 planets, the Sun, and the Moon — their positions calculated from simplified orbital models and updated live.

Features • Gyroscope sky map — point anywhere and the stars follow, at up to 120fps on supported devices • 16 constellations — tap any to see its mythology and star pattern • 110 Messier objects — galaxies, nebulae, and clusters plotted and tappable • Tap to lock on — tap any star or planet for its magnitude, coordinates, spectral type, and more • Sky search — find any object by name and jump to it instantly • Tonight's Sky — one tap shows what's visible right now: planets above the horizon, best deep-sky objects, and current moon phase • Time Machine — scrub forward or backward in time to plan or revisit a night • Observation journal — log your sightings with date, location, and notes • Celestial event alerts — get notified about oppositions, conjunctions, and lunar events for objects on your watch list • Milky Way overlay — the galactic band drawn across the sky • Red Night Mode — full red filter to protect your dark-adapted vision at the eyepiece • Share the sky — share a snapshot card of tonight's sky with friends • Portrait and landscape — works in any orientation on iPhone and iPad Honest about accuracy Star and planet positions use simplified orbital models this is great for finding constellations, identifying planets, and learning the night sky. For precise observation planning, pair it with a professional ephemeris.

Verdict
The clearest difference is price: TheosU at Free against DeepSpace's $0.99. TheosU also leads on ratings volume (82 vs 1) and iOS requirement (15.0 vs 26.0). DeepSpace's advantage is in-app purchases (none vs 5) and update cadence (every 5 days vs monthly). On ads and device support there is nothing between them.
