The clearest difference is rating: Clinometer Bubble Level at 3.9 against Angle Level's 3.3. Clinometer Bubble Level also leads on in-app purchases (none vs 1) and ratings volume (58 vs 3).

Both are free to download. Angle Level sells 1 one-off in-app purchase. Clinometer Bubble Level asks for nothing beyond the download.

Clinometer Bubble Level holds the better App Store score, 3.9 against 3.3.

Written reviews complicate that: 40% of Clinometer Bubble Level's written reviews are positive against 67% of Angle Level's, so the app with the better star average is not the one people write more warmly about.
