# Reptile Rocket vs KoiAi

The clearest difference is rating: KoiAi at 5.0 against Reptile Rocket's 4.3. KoiAi also leads on update cadence (every 2 weeks vs every 5 weeks). Reptile Rocket's advantage is ratings volume (99 vs 1) and iOS requirement (14.2 vs 18.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Reptile Rocket sells 2 in-app purchases, starting at $3.99 per month and KoiAi sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

KoiAi holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Reptile Rocket has 99 ratings behind it against 1, so its average is the more settled of the two.

Reptile Rocket ships an update every 5 weeks, KoiAi every 2 weeks. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
