Verdict

The call

The clearest difference is rating: LegitApp Authentication at 4.9 against KakoBuy's 3.6. LegitApp Authentication also leads on update cadence (weekly vs every 2 months) and ratings volume (9.9K vs 142). KakoBuy's advantage is monetization model (free vs free with in-app purchases) and chart position (#155 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.
