ReceptionRating · Positive reviews · Number of ratings

Grid Ref UTM holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Grid Ref UTM has 183 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 86% of DMS Converter's written reviews are positive against 74% of Grid Ref UTM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DMS Converter ships an update every 3 months, Grid Ref UTM every 10 months. The most recent releases landed on September 24, 2026 and October 7, 2026 respectively.
