# eBird vs PinProf

The clearest difference is review sentiment: PinProf at 100% against eBird's 37%. PinProf also leads on rating (4.8 vs 3.8) and update cadence (every 5 days vs monthly). eBird's advantage is ratings volume (803 vs 5) and chart position (#157 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.

PinProf holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: eBird has 803 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 37% of eBird's written reviews are positive against 100% of PinProf's.

eBird ships an update monthly, PinProf every 5 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
