Verdict
The clearest difference is rating: Orenda at 4.7 against Natural Pool's 3.0. Orenda also leads on ratings volume (478 vs 2). Natural Pool's advantage is review sentiment (100% vs 82%) and iOS requirement (10.0 vs 15.0). On price, update cadence, 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.
Orenda holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Orenda has 478 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of Orenda's written reviews are positive against 100% of Natural Pool's, so the app with the better star average is not the one people write more warmly about.
Orenda ships an update monthly, Natural Pool every 2 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
