Verdict

The call

The clearest difference is in-app purchases: Conversion! at none against App Lock's 1. Conversion! also leads on ads (none vs shown). App Lock's advantage is update cadence (every 2 weeks vs every 20 months) and iOS requirement (16.0 vs 26.0). On price and device support there is nothing between them.
