# Engineering Survey Calculator vs Coordinate Master

The clearest difference is review sentiment: Coordinate Master at 83% against Engineering Survey Calculator's 0%. Coordinate Master also leads on update cadence (fortnightly vs every 24 months) and ratings volume (5 vs 1). Engineering Survey Calculator's advantage is rating (5.0 vs 4.4) and price ($2.99 vs $3.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Engineering Survey Calculator costs $2.99 and Coordinate Master $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Engineering Survey Calculator holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Coordinate Master has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Engineering Survey Calculator's written reviews are positive against 83% of Coordinate Master's, so the app with the better star average is not the one people write more warmly about.

Engineering Survey Calculator ships an update every 24 months, Coordinate Master fortnightly. Both last shipped on September 18, 2026.
