Verdict

The call

The clearest difference is in-app purchases: HydroApp at none against Luma's 1. HydroApp also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). Luma's advantage is update cadence (every 2 days vs every 20 months). On price and device support there is nothing between them.
