# Viz.ai vs CNS+

The clearest difference is review sentiment: CNS+ at 100% against Viz.ai's 14%. CNS+ also leads on rating (5.0 vs 4.2) and iOS requirement (13.0 vs 17.0). Viz.ai's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (36 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

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

CNS+ holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Viz.ai has 36 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 14% of Viz.ai's written reviews are positive against 100% of CNS+'s.

Viz.ai ships an update fortnightly, CNS+ every 4 months. The most recent releases landed on October 3, 2026 and September 22, 2026 respectively.
