Verdict
The clearest difference is in-app purchases: Decypher at none against Icon Killer's 1. Decypher also leads on ads (none vs shown) and update cadence (daily vs every 6 days). Icon Killer's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price there is nothing between them.
