Verdict
The clearest difference is review sentiment: SmartSDR™ at 77% against AntScope's 21%. SmartSDR™ also leads on rating (4.3 vs 2.3) and update cadence (every 2 weeks vs every 3 months). AntScope's advantage is price (Free vs $79.99) and in-app purchases (none vs 10). On ratings volume, ads, monetization model and device support there is nothing between them.
