Verdict
The clearest difference is in-app purchases: Sound Scope Analyzer at none against HushStep's 1. Sound Scope Analyzer also leads on update cadence (daily vs every 3 weeks). HushStep's advantage is ads (none vs shown) and iOS requirement (16 vs 26.5). On price and device support there is nothing between them.
