# Saturation Index Calculator vs EquateAccess

The clearest difference is rating: Saturation Index Calculator at 4.3 against EquateAccess's 1.3. Saturation Index Calculator also leads on iOS requirement (10.2 vs 14). EquateAccess's advantage is ratings volume (227 vs 4) and chart position (#170 vs unranked). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Saturation Index Calculator holds the better App Store score, 4.3 against 1.3. That said, the two scores are not equally well evidenced: EquateAccess has 227 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of Saturation Index Calculator's written reviews are positive against 1% of EquateAccess's, so the app with the better star average is not the one people write more warmly about.
