Verdict
The clearest difference is price: Anti at Free against Sinus ID's $4.99. Anti also leads on rating (3.0 vs 1.5) and update cadence (every 10 days vs every 40 months). Sinus ID's advantage is in-app purchases (none vs 1). On review sentiment, ratings volume, ads and device support there is nothing between them.
