# OCO vs Saturn Slalom

The clearest difference is update cadence: Saturn Slalom at every 2 days against OCO's every 5 weeks. Saturn Slalom also leads on iOS requirement (13.0 vs 15.0). OCO's advantage is ratings volume (2.4K vs 169). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. OCO sells 8 one-off in-app purchases and Saturn Slalom sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for OCO against 4.6 for Saturn Slalom. That said, the two scores are not equally well evidenced: OCO has 2.4K ratings behind it against 169, so its average is the more settled of the two. Written reviews are what separate them: 73% of OCO's written reviews are positive against 71% of Saturn Slalom's.

OCO ships an update every 5 weeks, Saturn Slalom every 2 days. Both last shipped on October 26, 2026.
