# ExplosionMotor vs Coloring Your ZOO

The clearest difference is price: Coloring Your ZOO at Free against ExplosionMotor's $0.99. Coloring Your ZOO also leads on rating (4.5 vs 4.0) and update cadence (every 2 months vs every 39 months). ExplosionMotor's advantage is in-app purchases (none vs 3). On review sentiment, ads and device support there is nothing between them.

Coloring Your ZOO is free to download; ExplosionMotor costs $0.99 up front. Coloring Your ZOO sells 3 one-off in-app purchases. ExplosionMotor asks for nothing beyond the download.

Coloring Your ZOO holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Coloring Your ZOO has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ExplosionMotor's written reviews are positive against 98% of Coloring Your ZOO's, so the app with the better star average is not the one people write more warmly about.

ExplosionMotor ships an update every 39 months, Coloring Your ZOO every 2 months. The most recent releases landed on October 28, 2026 and October 21, 2026 respectively.
