# eBird vs Quill

The clearest difference is rating: Quill at 5.0 against eBird's 3.8. Quill also leads on iOS requirement (15.1 vs 18.0). eBird's advantage is ratings volume (827 vs 1) and chart position (#169 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Quill holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: eBird has 827 ratings behind it against 1, so its average is the more settled of the two.
