# Neurosurgery vs CNS+

The clearest difference is in-app purchases: CNS+ at none against Neurosurgery's 1. CNS+ also leads on review sentiment (100% vs 77%) and update cadence (every 4 months vs every 21 months). Neurosurgery's advantage is ratings volume (92 vs 4). On price, rating and ads there is nothing between them.

Both are free to download. Neurosurgery sells 1 in-app purchase, starting at $2.99 per year. CNS+ asks for nothing beyond the download.

CNS+ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Neurosurgery has 92 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 77% of Neurosurgery's written reviews are positive against 100% of CNS+'s.

Neurosurgery ships an update every 21 months, CNS+ every 4 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
