Verdict
The clearest difference is review sentiment: SDR at 80% against AntScope's 23%. SDR also leads on rating (4.2 vs 2.3) and update cadence (every 2 weeks vs every 2 months). AntScope's advantage is price (Free vs $49.99) and device support (3 vs 1). On ratings volume, ads and in-app purchases there is nothing between them.
