Verdict
The clearest difference is price: Audubon Bird Guide at Free against Coton's $1.99. Audubon Bird Guide also leads on rating (4.3 vs 3.5) and update cadence (every 3 weeks vs every 5 months). Coton's advantage is ads (none vs shown) and review sentiment (77% vs 64%). On in-app purchases and device support there is nothing between them.

Audubon Bird Guide is free to download; Coton costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Audubon Bird Guide holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: Audubon Bird Guide has 4.5K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 64% of Audubon Bird Guide's written reviews are positive against 77% of Coton's, so the app with the better star average is not the one people write more warmly about.
Audubon Bird Guide ships an update every 3 weeks, Coton every 5 months. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
