Verdict

The call

The clearest difference is rating: Worm Stack at 4.7 against Rainbow Snake!'s 3.4. Worm Stack also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (1.7K vs 8). Rainbow Snake!'s advantage is in-app purchases (none vs 12). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Worm Stack holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Worm Stack has 1.7K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 60% of Rainbow Snake!'s written reviews are positive against 52% of Worm Stack's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Rainbow Snake! ships an update every 3 months, Worm Stack every 2 weeks. The most recent releases landed on September 20, 2026 and October 1, 2026 respectively.
