Verdict

The call

The clearest difference is ads: KxCoding at none against InterviewWorkout's shown. KxCoding also leads on device support (3 vs 1). InterviewWorkout's advantage is update cadence (every 3 weeks vs every 3 months). On price, in-app purchases and iOS requirement there is nothing between them.
