# Galaxy Map vs Terra

The clearest difference is in-app purchases: Terra at none against Galaxy Map's 13. Terra also leads on ads (none vs shown) and rating (5.0 vs 4.6). Galaxy Map's advantage is ratings volume (609 vs 1) and update cadence (monthly vs every 3 months). On price and device support there is nothing between them.

Both are free to download. Galaxy Map sells 13 one-off in-app purchases. Terra asks for nothing beyond the download.

Terra holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Galaxy Map has 609 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 80% of Galaxy Map's written reviews are positive against 100% of Terra's.

Galaxy Map ships an update monthly, Terra every 3 months. The most recent releases landed on October 16, 2026 and October 7, 2026 respectively.
