Verdict
The clearest difference is price: Space BlocKing at Free against Silverfish DX's $1.99. Space BlocKing also leads on update cadence (monthly vs every 21 months). Silverfish DX's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On in-app purchases and device support there is nothing between them.
