Strike and Dip holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Theodolite has 906 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 46% of Strike and Dip's written reviews are positive against 88% of Theodolite's, so the app with the better star average is not the one people write more warmly about.

Strike and Dip ships an update every 9 months, Theodolite every 4 months. Both last shipped on October 27, 2026.
