# Sine Mora vs Atlantis Invaders

The clearest difference is price: Atlantis Invaders at Free against Sine Mora's $4.99. Atlantis Invaders also leads on rating (4.7 vs 3.7) and ratings volume (2.8K vs 21). Sine Mora's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support there is nothing between them.

Atlantis Invaders is free to download; Sine Mora costs $4.99 up front. Atlantis Invaders sells 10 one-off in-app purchases. Sine Mora asks for nothing beyond the download.

Atlantis Invaders holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Atlantis Invaders has 2.8K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 43% of Sine Mora's written reviews are positive against 31% of Atlantis Invaders's, so the app with the better star average is not the one people write more warmly about.

Sine Mora ships an update every 3 months, Atlantis Invaders fortnightly. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
