# CNS+ vs Surgical Preparation App

The clearest difference is update cadence: Surgical Preparation App at every 3 days against CNS+'s every 4 months. CNS+'s advantage is iOS requirement (13.0 vs 18.5). On price, ads, in-app purchases and device support there is nothing between them.

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

CNS+ ships an update every 4 months, Surgical Preparation App every 3 days. The most recent releases landed on November 3, 2026 and November 9, 2026 respectively.
