# CortexScan vs Atos OneContact

The clearest difference is rating: Atos OneContact at 4.0 against CortexScan's 3.0. Atos OneContact also leads on update cadence (every 5 weeks vs every 3 months) and iOS requirement (12.3 vs 16.0). CortexScan's advantage is ratings volume (23 vs 4). 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.

Atos OneContact holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: CortexScan has 23 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 38% of CortexScan's written reviews are positive against 33% of Atos OneContact's, so the app with the better star average is not the one people write more warmly about.

CortexScan ships an update every 3 months, Atos OneContact every 5 weeks. The most recent releases landed on October 16, 2026 and October 10, 2026 respectively.
