# Exoplanet vs AGILEScience

The clearest difference is in-app purchases: AGILEScience at none against Exoplanet's 7. AGILEScience also leads on review sentiment (100% vs 91%) and iOS requirement (8.0 vs 13.0). Exoplanet's advantage is update cadence (every 2 weeks vs every 3 months) and device support (4 vs 2). On price and ads there is nothing between them.

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

Exoplanet ships an update every 2 weeks, AGILEScience every 3 months. The most recent releases landed on October 26, 2026 and October 12, 2026 respectively.
