Verdict

The call

The clearest difference is in-app purchases: One Elite Training at none against Hydrium's 2. One Elite Training also leads on device support (4 vs 2) and iOS requirement (15.1 vs 17.0). Hydrium's advantage is update cadence (every 4 days vs every 2 months). On price and ads there is nothing between them.
