Verdict

The call

The clearest difference is in-app purchases: NumberSkeleton at none against Happy Link's 7. NumberSkeleton also leads on update cadence (every 3 days vs every 20 months). Happy Link's advantage is iOS requirement (14.0 vs 17.6). On price, ads and device support there is nothing between them.
