Verdict

The call

The clearest difference is in-app purchases: MiU at none against Vaia's 17. MiU also leads on review sentiment (100% vs 81%) and iOS requirement (13.0 vs 17.0). Vaia's advantage is ratings volume (1.6K vs 9) and update cadence (weekly vs monthly). On price, rating, ads and device support there is nothing between them.
