Verdict

The call

The clearest difference is in-app purchases: Red Calm at none against Harmony's 18. Red Calm also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.4). Harmony's advantage is update cadence (every 6 days vs monthly). On price and device support there is nothing between them.
