Verdict
The clearest difference is monetization model: ZenWorkout at free with in-app purchases against AI Workout Timer's subscription. ZenWorkout also leads on update cadence (daily vs fortnightly) and iOS requirement (13.0 vs 15.1). AI Workout Timer's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and device support there is nothing between them.
