# Galaxy Defender+ vs Atlantis Invaders

The clearest difference is in-app purchases: Galaxy Defender+ at none against Atlantis Invaders's 70. Galaxy Defender+ also leads on ads (none vs shown) and rating (5.0 vs 4.7). Atlantis Invaders's advantage is ratings volume (2.8K vs 1) and update cadence (fortnightly vs every 6 weeks). On price and device support there is nothing between them.

Both are free to download. Atlantis Invaders sells 70 one-off in-app purchases. Galaxy Defender+ asks for nothing beyond the download.

Galaxy Defender+ holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Atlantis Invaders has 2.8K ratings behind it against 1, so its average is the more settled of the two.

Galaxy Defender+ ships an update every 6 weeks, Atlantis Invaders fortnightly. The most recent releases landed on October 10, 2026 and October 22, 2026 respectively.
