Verdict

The call

The clearest difference is in-app purchases: HSY at none against Age Checker's 1. HSY also leads on ads (none vs shown) and iOS requirement (9.0 vs 16.0). Age Checker's advantage is update cadence (every 3 months vs every 24 months). On price and device support there is nothing between them.
