# Viz.ai vs NeuroStudy

The clearest difference is review sentiment: NeuroStudy at 100% against Viz.ai's 14%. NeuroStudy also leads on rating (5.0 vs 4.2) and iOS requirement (13.0 vs 17.0). Viz.ai's advantage is in-app purchases (none vs 1) and update cadence (fortnightly vs every 6 months). On price, ads and device support there is nothing between them.

Both are free to download. NeuroStudy sells 1 one-off in-app purchase. Viz.ai asks for nothing beyond the download.

NeuroStudy 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 1, 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 NeuroStudy's.

Viz.ai ships an update fortnightly, NeuroStudy every 6 months. The most recent releases landed on October 3, 2026 and October 6, 2026 respectively.
