Verdict
The clearest difference is price: Audubon Bird Guide at Free against Net Knots's $3.99. Audubon Bird Guide also leads on update cadence (every 3 weeks vs every 12 months) and ratings volume (4.5K vs 10). Net Knots's advantage is review sentiment (100% vs 64%) and ads (none vs shown). On in-app purchases and device support there is nothing between them.
