# Polygon ID vs DORPLIJ

The clearest difference is rating: DORPLIJ at 5.0 against Polygon ID's 4.3. Polygon ID's advantage is ratings volume (7 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

DORPLIJ holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Polygon ID has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
