Verdict

The call

The clearest difference is price: Photomath at Free against Calculator ∞'s $5.99. Photomath also leads on ratings volume (733K vs 6.3K) and update cadence (monthly vs every 2 months). Calculator ∞'s advantage is review sentiment (75% vs 51%) and iOS requirement (12.1 vs 14.0). On rating, ads, in-app purchases and monetization model there is nothing between them.
