Verdict
The clearest difference is in-app purchases: Simple Reaction Timer at none against Dynamix's 17. Simple Reaction Timer also leads on update cadence (daily vs every 6 weeks). Dynamix's advantage is ads (none vs shown) and iOS requirement (11.0 vs 17.6). On price and device support there is nothing between them.
