# Backline+ vs Viz.ai

The clearest difference is rating: Viz.ai at 4.2 against Backline+'s 2.4. Viz.ai also leads on update cadence (fortnightly vs monthly). Backline+'s advantage is review sentiment (25% vs 14%). On price, ratings volume, ads and in-app purchases there is nothing between them.

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

Viz.ai holds the better App Store score, 4.2 against 2.4. Both are backed by a comparable volume of ratings — 33 and 36 respectively. Written reviews complicate that: 25% of Backline+'s written reviews are positive against 14% of Viz.ai's, so the app with the better star average is not the one people write more warmly about.

Backline+ ships an update monthly, Viz.ai fortnightly. The most recent releases landed on August 21, 2026 and September 16, 2026 respectively.
