# Core Anesthesia vs PreOpApp Kids

The clearest difference is monetization model: PreOpApp Kids at free against Core Anesthesia's free with in-app purchases. PreOpApp Kids also leads on update cadence (every 11 days vs every 3 weeks) and review sentiment (100% vs 90%). Core Anesthesia's advantage is ratings volume (537 vs 17) and chart position (#196 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Core Anesthesia sells 14 in-app purchases, starting at $9.99 per month and PreOpApp Kids sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Core Anesthesia against 4.9 for PreOpApp Kids. That said, the two scores are not equally well evidenced: Core Anesthesia has 537 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 90% of Core Anesthesia's written reviews are positive against 100% of PreOpApp Kids's.

Core Anesthesia ships an update every 3 weeks, PreOpApp Kids every 11 days. Both last shipped on October 24, 2026.
