Verdict

The call

The clearest difference is in-app purchases: Moon Book at none against Daff Moon's 2. Moon Book also leads on ads (none vs shown) and device support (3 vs 1). Daff Moon's advantage is update cadence (every 2 weeks vs every 6 months) and review sentiment (100% vs 90%). On price there is nothing between them.
