Verdict
The clearest difference is in-app purchases: Human Heart at none against ReadingLog's 1. Human Heart also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.0). ReadingLog's advantage is update cadence (monthly vs every 37 months). On price and device support there is nothing between them.
