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.

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.
