# Photon Mobile vs Viz.ai

The clearest difference is review sentiment: Photon Mobile at 80% against Viz.ai's 14%. Photon Mobile also leads on iOS requirement (15.0 vs 17.0). Viz.ai's advantage is rating (4.2 vs 3.8) and update cadence (fortnightly vs every 2 months). 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.

Viz.ai holds the better App Store score, 4.2 against 3.8. Both are backed by a comparable volume of ratings — 8 and 36 respectively. Written reviews complicate that: 80% of Photon Mobile'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.

Photon Mobile ships an update every 2 months, Viz.ai fortnightly. The most recent releases landed on October 7, 2026 and October 20, 2026 respectively.
