Cosmic Watch vs Seestar App

Cosmic Watch combines a 3D planetarium, sky guide and clock, rendering Earth and the sky in real time. Point a phone or tablet toward the sky to identify constellations, stars and planets through augmented reality. Views cover the observer’s location, Earth and the solar system; the app also includes geocentric and heliocentric solar-system views, a 360-degree celestial sphere, astrology mode, retrograde motion, a world clock and astronomical-event notifications. A free plan includes the sky guide, views, layers, star names, world clock and notifications. Paid tools add options such as Moon Calendar, meteor showers, saved date, time and location, and Time Control. Cosmic Astro offers Western or Vedic natal charts with interactive 3D horoscopes and PDF export to subscribers and Cosmic Pro members. Cosmic Watch is available for Android, iOS and macOS. Optional self-hosted Matomo analytics can be disabled in settings; the maker says it does not store or share location or network information. The maker presents the app as an educational tool for astronomy concepts and Earth cycles.

Seestar App controls Seestar telescopes and supports astronomical observation and imaging. Its Stargazing mode can find and focus on celestial objects, track them, and capture and process images automatically. The app also offers Scenery, Solar, and Lunar modes; solar and lunar targets can be tracked automatically, while Scenery provides manual direction control and autofocus. SkyAtlas supports searching celestial targets, viewing basic information, and one-tap GoTo alignment. The Home tab includes a gallery, shooting plans, and post-processing tools, alongside telescope settings, firmware updates, and battery and storage information. The maker says the app works with all Seestar models. For the S30 Pro, listed capabilities include a catalogue of 80,000+ deep-sky objects and 600,000+ stars, scheduled observing, remote control, and mosaic stitching. The S50 connects to a mobile device over its own Wi-Fi without internet, though internet is needed for first activation, accounts, data loading, Square features, and updates. The app is free and listed for Android, iOS, macOS, and Windows.
