# 角度测量仪 vs Protractor

The clearest difference is rating: 角度测量仪 at 5.0 against Protractor's 1.8. 角度测量仪 also leads on in-app purchases (none vs 2) and iOS requirement (12.0 vs 17.0). Protractor's advantage is review sentiment (64% vs 50%) and ratings volume (6 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Protractor sells 2 one-off in-app purchases. 角度测量仪 asks for nothing beyond the download.

角度测量仪 holds the better App Store score, 5.0 against 1.8. That said, the two scores are not equally well evidenced: Protractor has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of 角度测量仪's written reviews are positive against 64% of Protractor's, so the app with the better star average is not the one people write more warmly about.
