Verdict

The call

The clearest difference is in-app purchases: Defender HD at none against NetSpot WiFi Analyzer's 3. Defender HD also leads on review sentiment (25% vs 15%) and iOS requirement (12.0 vs 15.5). NetSpot WiFi Analyzer's advantage is rating (3.7 vs 3.3) and update cadence (every 2 weeks vs every 3 months). On price, ratings volume, ads and device support there is nothing between them.
