Verdict
The clearest difference is in-app purchases: Ka at none against Yes / No Button's 1. Ka also leads on iOS requirement (9.3 vs 15.0). Yes / No Button's advantage is ads (none vs shown) and review sentiment (52% vs 25%). On price, rating, update cadence and device support there is nothing between them.
