# Final Surge vs KoopAI

The clearest difference is rating: KoopAI at 5.0 against Final Surge's 3.8. Final Surge's advantage is ratings volume (125 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Final Surge sells 2 in-app purchases, starting at $9.99 per month and KoopAI sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

KoopAI holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Final Surge has 125 ratings behind it against 2, so its average is the more settled of the two.
