Verdict
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.
