# NASA vs Satellite Chasers

The clearest difference is in-app purchases: NASA at none against Satellite Chasers's 2. NASA also leads on ratings volume (64K vs 26) and rating (4.8 vs 4.5). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Satellite Chasers sells 2 one-off in-app purchases. NASA asks for nothing beyond the download.

NASA holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: NASA has 64K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 70% of NASA's written reviews are positive against 75% of Satellite Chasers's, so the app with the better star average is not the one people write more warmly about.

NASA ships an update every 2 weeks, Satellite Chasers every 5 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
