# Viz.ai vs Zebdoc

The clearest difference is rating: Zebdoc at 5.0 against Viz.ai's 4.2. Zebdoc also leads on iOS requirement (15.1 vs 17.0). Viz.ai's advantage is ratings volume (36 vs 1) and update cadence (fortnightly vs every 5 weeks). 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.

Zebdoc 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 complicate that: 14% of Viz.ai's written reviews are positive against 0% of Zebdoc's, so the app with the better star average is not the one people write more warmly about.

Viz.ai ships an update fortnightly, Zebdoc every 5 weeks. Both last shipped on October 24, 2026.
