# Exoplanet vs Earth Rotation

The clearest difference is price: Exoplanet at Free against Earth Rotation's $0.99. Exoplanet also leads on update cadence (every 2 weeks vs every 22 months) and ratings volume (978 vs 1). Earth Rotation's advantage is in-app purchases (none vs 7) and rating (5.0 vs 4.7). On ads and device support there is nothing between them.

Exoplanet is free to download; Earth Rotation costs $0.99 up front. Exoplanet sells 7 one-off in-app purchases. Earth Rotation asks for nothing beyond the download.

Earth Rotation holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Exoplanet has 978 ratings behind it against 1, so its average is the more settled of the two.

Exoplanet ships an update every 2 weeks, Earth Rotation every 22 months. The most recent releases landed on October 31, 2026 and October 30, 2026 respectively.
