Verdict

The call

The clearest difference is rating: Audubon Bird Guide at 4.3 against eBird's 3.8. Audubon Bird Guide also leads on review sentiment (64% vs 37%) and ratings volume (4.5K vs 803). eBird's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.
