Verdict
The clearest difference is in-app purchases: Secret Message at none against App Lock's 7. Secret Message also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.0). App Lock's advantage is update cadence (fortnightly vs every 8 months). On price and device support there is nothing between them.
