Verdict

The call

The clearest difference is ads: Kakeizu at none against Relmap's shown. Kakeizu also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.0). Relmap's advantage is update cadence (every 2 days vs every 6 days). On price and in-app purchases there is nothing between them.
