ReceptionRating · Positive reviews · Number of ratings

Petrix Maps Oilfield Navigator holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: Petrix Maps Oilfield Navigator has 275 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Drillstring Toolbox's written reviews are positive against 64% of Petrix Maps Oilfield Navigator's, so the app with the better star average is not the one people write more warmly about.
