# Mars Rover Tracker vs Earth Maps

The clearest difference is in-app purchases: Mars Rover Tracker at none against Earth Maps's 4. Mars Rover Tracker also leads on rating (5.0 vs 4.8). Earth Maps's advantage is review sentiment (79% vs 50%) and ratings volume (1.2K vs 4). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Earth Maps sells 4 one-off in-app purchases. Mars Rover Tracker asks for nothing beyond the download.

Mars Rover Tracker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Earth Maps has 1.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Mars Rover Tracker's written reviews are positive against 79% of Earth Maps's, so the app with the better star average is not the one people write more warmly about.

Mars Rover Tracker ships an update monthly, Earth Maps every 3 weeks. The most recent releases landed on September 18, 2026 and September 27, 2026 respectively.
