# Guroku Rainbow vs Polyloop

The clearest difference is ads: Polyloop at none against Guroku Rainbow's shown. Guroku Rainbow's advantage is ratings volume (22 vs 1) and iOS requirement (12.0 vs 15.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Guroku Rainbow sells 1 one-off in-app purchase and Polyloop sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Polyloop holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Guroku Rainbow has 22 ratings behind it against 1, so its average is the more settled of the two.
