Verdict
The clearest difference is in-app purchases: KINROKU at none against RowPower's 1. KINROKU also leads on iOS requirement (15.1 vs 18.2). RowPower's advantage is ads (none vs shown) and update cadence (every 4 days vs every 11 days). On price and device support there is nothing between them.
