Verdict
The clearest difference is in-app purchases: Core Master at none against ZenWorkout's 1. Core Master also leads on ads (none vs shown). ZenWorkout's advantage is update cadence (daily vs every 7 months) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
