Verdict

The call

The clearest difference is rating: Mach Dice at 4.7 against Vay's 4.0. Mach Dice also leads on price ($0.99 vs $5.99) and review sentiment (85% vs 73%). Vay's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 17 months). On ads and device support there is nothing between them.
