Verdict
The clearest difference is in-app purchases: HelixAI at none against Workout Builder's 1. HelixAI also leads on device support (3 vs 1) and iOS requirement (13.4 vs 17.0). Workout Builder's advantage is update cadence (fortnightly vs monthly). On price and ads there is nothing between them.
