Verdict
The clearest difference is review sentiment: SDR at 84% against AntScope's 21%. SDR also leads on rating (4.6 vs 2.3) and update cadence (every 2 weeks vs every 3 months). AntScope's advantage is price (Free vs $44.99) and device support (3 vs 1). On ratings volume, ads and in-app purchases there is nothing between them.
