Verdict
The clearest difference is in-app purchases: Devplay at none against Katsuyou Drill's 1. Devplay also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Katsuyou Drill's advantage is update cadence (weekly vs every 3 months). On price and device support there is nothing between them.
