# BlendZ vs NDI Multiview

The clearest difference is price: NDI Multiview at Free against BlendZ's $0.99. NDI Multiview also leads on update cadence (every 2 weeks vs every 4 months) and rating (4.0 vs 3.7). BlendZ's advantage is in-app purchases (none vs 4) and review sentiment (75% vs 46%). On ads, monetization model and device support there is nothing between them.

NDI Multiview is free to download; BlendZ costs $0.99 up front. NDI Multiview sells 4 one-off in-app purchases. BlendZ asks for nothing beyond the download.

NDI Multiview holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: NDI Multiview has 128 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 75% of BlendZ's written reviews are positive against 46% of NDI Multiview's, so the app with the better star average is not the one people write more warmly about.

BlendZ ships an update every 4 months, NDI Multiview every 2 weeks. The most recent releases landed on October 10, 2026 and October 14, 2026 respectively.
