Verdict
The clearest difference is monetization model: KHR at free against SleepScore Max's free with in-app purchases. KHR also leads on rating (5.0 vs 4.6). SleepScore Max's advantage is ratings volume (446 vs 2) and iOS requirement (11.2 vs 15.1). On price, update cadence, ads and in-app purchases there is nothing between them.
