Using the Coordinator app, you can collect coordinate data from land in any coordinate system you choose, from predefined systems. You can collect GPS coordinates. You can use the app as a GPS tracker. You can view the coordinate data on the map. You can search by longitude/latitude. You can convert an existing coordinate into another coordinate system. You can display circumference and area measurements for some coordinates by opening the file created earlier. Also, you can measure distances and areas for coordinates marked on the map manually. You can display a KML file on the map. The coordinator app contains several useful tools for people interested in coordinates, maps, and geographic information systems (GIS). The coordinator offers Cloud Database Functions (creating points, lines & polygons; sharing your layers with teammates; working simultaneously with teammates; working offline and synchronizing; etc.), exporting to KML & Excel files, retrieving the elevation value of points, and so on. You can create your layers and share those layers with your teammates. You can instantly see the data created by other friends on the map. In addition to longitude/latitude, subscribers can find the altitude of a point on the map. Subscribers can use the Coordinator Web app. So you can use the cloud database features of the Coordinator app on your computer's web page and monitor the data instantly. You can view/track and edit cloud database data on the web page. In this way, you can instantly monitor data movements in the mobile app in the field and in the web browser on your computer. The coordinate systems of the countries where the app is most downloaded are added to the app. Current list of countries and their coordinate systems defined in this app: World - GPS(WGS 84) World - WGS 84 - 6 UTM United States - "NAD 1983 HARN State Plane Coordinate Systems(meters & feet)" and "Military Grid Reference System (MGRS)" Algeria - "Nord Sahara 1959 / UTM 6 " Azerbaijan - "Pulkovo 1942 / Gauss-Kruger 3 " and "Pulkovo 1942 / CS63" Bulgaria - "Pulkovo 1942(58) GK 6 " Germany - "DHDN/3 GK" and "ETRS89 UTM 6" India - "Kalianpur 1975 / India" and "Kalianpur 1975 / UTM 6" Indonesia - "Indonesia 1974 UTM 6" and "DGN 1995 Indonesia TM3" Iran - "ED50(ED77) / UTM 6" Iraq - "Nahrwan 1967 / UTM 6", "ED50 / Iraq National Grid", and "Karbala 1979 / UTM 6" Israel - "Palestine 1923/Palest.

Verdict

The call

The clearest difference is rating: Grid Ref UTM at 4.6 against GPS Coordinates & Map Tools's 2.7. Grid Ref UTM also leads on ads (none vs shown) and ratings volume (183 vs 6). GPS Coordinates & Map Tools's advantage is review sentiment (100% vs 74%) and update cadence (every 2 months vs every 10 months). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Grid Ref UTM holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Grid Ref UTM has 183 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 74% of Grid Ref UTM's written reviews are positive against 100% of GPS Coordinates & Map Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Grid Ref UTM ships an update every 10 months, GPS Coordinates & Map Tools every 2 months. The most recent releases landed on October 7, 2026 and September 28, 2026 respectively.
