SkyScope is free to download and works without an account. Take or import a night-sky photo for an AI-assisted identification. No AR calibration or compass setup is needed. WHAT'S INSIDE • Scan: take a new photo or import one from your library; see the primary constellation, confidence explanation, object counts, named stars, and a concise astronomy fact • Compare candidates when the visual match is uncertain • See location and time as observation context, separate from the visual estimate • Explore tab: browse planets, stars, constellations, and deep-sky objects by category FREE RESULT shows the primary constellation, stats, an astronomy fact, and the first two named stars. Premium adds observing context, all named stars, planet candidates, and moon details when detected. IMPORTANT SkyScope is an astronomy and reference app — not an astrology app. Results are estimates; use the suggested photo and candidate checks before treating a match as certain. Premium is available as a Weekly Premium auto-renewable subscription or Lifetime Premium (one-time purchase), depending on your App Store region. Prices may vary by country or region.
