# Compatibility vs Supplements AI

The clearest difference is rating: Supplements AI at 4.3 against Compatibility's 3.9. Supplements AI also leads on update cadence (every 4 days vs every 2 weeks) and ratings volume (122 vs 11). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Compatibility sells 2 in-app purchases, starting at $1.99 per month and Supplements AI sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Supplements AI holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Supplements AI has 122 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 60% of Compatibility's written reviews are positive against 55% of Supplements AI's, so the app with the better star average is not the one people write more warmly about.

Compatibility ships an update every 2 weeks, Supplements AI every 4 days. The most recent releases landed on September 24, 2026 and September 15, 2026 respectively.
