Verdict
The clearest difference is in-app purchases: Rhythm Master at none against Water Eject / Speaker Cleaner's 4. Rhythm Master also leads on iOS requirement (14.0 vs 17.0). Water Eject / Speaker Cleaner's advantage is ads (none vs shown) and update cadence (every 10 days vs every 8 months). On price and device support there is nothing between them.
