# Pool vs LoyalAI

The clearest difference is review sentiment: LoyalAI at 73% against Pool's 22%. LoyalAI also leads on price (Free vs $4.99) and update cadence (weekly vs every 5 weeks). Pool's advantage is in-app purchases (none vs 10) and ratings volume (629 vs 13). On ads and iOS requirement there is nothing between them.

LoyalAI is free to download; Pool costs $4.99 up front. LoyalAI sells 10 in-app purchases, starting at $9.99 per month. Pool asks for nothing beyond the download.

Pool holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Pool has 629 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 22% of Pool's written reviews are positive against 73% of LoyalAI's, so the app with the better star average is not the one people write more warmly about.

Pool ships an update every 5 weeks, LoyalAI weekly. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
