Verdict
The clearest difference is in-app purchases: Sis at none against Onset Workouts's 2. Sis also leads on ads (none vs shown) and iOS requirement (15.1 vs 26.5). Onset Workouts's advantage is update cadence (every 2 days vs every 3 months). On price and device support there is nothing between them.
