# Exoplanet vs Solar System

The clearest difference is rating: Exoplanet at 4.7 against Solar System's 3.7. Exoplanet also leads on update cadence (every 2 weeks vs every 107 months) and review sentiment (91% vs 67%). Solar System's advantage is in-app purchases (none vs 7). On price and ads there is nothing between them.

Both are free to download. Exoplanet sells 7 one-off in-app purchases. Solar System asks for nothing beyond the download.

Exoplanet holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Exoplanet has 975 ratings behind it against 30, so its average is the more settled of the two. Written reviews point the same way: 91% of Exoplanet's written reviews are positive against 67% of Solar System's.

Exoplanet ships an update every 2 weeks, Solar System every 107 months. Both last shipped on October 26, 2026.
