# NeuroVIZR vs Katalyst

The clearest difference is in-app purchases: Katalyst at none against NeuroVIZR's 6. NeuroVIZR's advantage is update cadence (weekly vs every 4 weeks) and rating (4.8 vs 4.6). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. NeuroVIZR sells 6 in-app purchases, starting at $8.89 per month. Katalyst asks for nothing beyond the download.

NeuroVIZR holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 113 and 59 respectively. Written reviews complicate that: 75% of NeuroVIZR's written reviews are positive against 81% of Katalyst's, so the app with the better star average is not the one people write more warmly about.

NeuroVIZR ships an update weekly, Katalyst every 4 weeks. The most recent releases landed on October 21, 2026 and October 22, 2026 respectively.
