Verdict
The clearest difference is in-app purchases: Kata Calc at none against Kumite Analysis's 8. Kata Calc also leads on ads (none vs shown) and iOS requirement (9.3 vs 17.0). Kumite Analysis's advantage is update cadence (every 10 days vs every 7 months). On price and device support there is nothing between them.
