Verdict
The clearest difference is price: DontSpam at Free against Blue Defense!'s $0.99. DontSpam also leads on rating (5.0 vs 4.1) and review sentiment (100% vs 84%). Blue Defense!'s advantage is ads (none vs shown) and ratings volume (9 vs 1). On update cadence, in-app purchases, device support and iOS requirement there is nothing between them.
