Read full description

Complete, simple, easy to use & free application for Land Surveying, Topography, Bathymetry & GIS. Suitable for Geodesy Engineering, Civil Engineering, Geology and other disciplines related to maps, coordinates, location, address and spatial analysis. Can be used as a tool in determining position, coordinates, location & address, area & distance measurement, simple spatial analysis such as Overlay, Buffering and finding coordinate location on the field / stake out. Map Coordinates: Can be used to obtain Latitude Longitude, UTM, MGRS and other Coordinate Reference System using EPSG Codes in real time. Plot points complete with coordinate data, addresses, notes, photo and MSL elevation (premium). Export saved points to CSV, DXF or KML files. Offline GPS: Used to get coordinates in an offline state (without internet access), your cellphone will function like a Handheld GPS to get Latitude Longitude coordinates, UTM, MGRS, Elevation (ellipsoid), MSL Elevation (geoid), accuracy and other useful information. Coordinates data can be stored in an unlimited number inside your databases, given notes / labels, photos or exported into CSV files. Contours: Module to generate contours based on number of contour lines, desired elevation or contour interval. This is premium module and need internet connection. Coordinates Converter: To convert coordinates manually from Latitude Longitude to UTM & MGRS and vice versa. It can also be used to convert Addresses to Coordinates (Geocoding). Area/Distance: Used to measure distance and area with various units (support units: m, km, ft, miles, hectare, acre), register lines / polygons, make polygons automatically from measure points using sophisticated Convex Hull, Concave Hull or Trace ID methods. Create polygon holes manually or automatically from covered polygons. Automatically repair invalid geometry / self-crossing polygons, and much more. You can store unlimited lines / polygons in your database, displayed on a map, add photos and labels or exported to CSV or KML files. This module also includes spatial editing algorithms like Snap Nearest, Delete Object Inside or Outside Polygon. Buffer/Overlay: Simple GIS module to perform spatial analysis such as buffering & overlays (and other GIS operations) with several options including Union, Intersection, Difference and Symmetrical Difference. Already support negative buffer for polygons. Find Point: Module to find a location or coordinates in the field / Stake Out using built in GPS and Compass on your cell phone. Compass Map: Module with Maps, Compass, Distance and Azimuth to assist navigation and stake out on the field. Elevation Profile: Premium module to create simple Elevation Profile, this module needs internet connection. Bubble Level module: measuring tool to calculate leveling, degree of slope and percentage of slope. DTM Module: generating TIN (Triangulated Irregular Network / Delaunay Triangulation) DTM from random points or existing contour data, calculating cut and fill volumes (including determining the optimal cut-and-fill reference level where volumes are nearly balanced), performing contour interpolation, etc.. Some other modules. Any suggestions are welcome, please submit via email to utmgeomapapp@gmail.com or write a review. Thanks.

Verdict

The call

The clearest difference is rating: Tomstrails GPS UTM at 4.8 against UTM Geo Map Y2Tech's 3.8. Tomstrails GPS UTM also leads on ads (none vs shown) and ratings volume (1.6K vs 4). UTM Geo Map Y2Tech's advantage is update cadence (fortnightly vs every 6 weeks) and review sentiment (100% vs 84%). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Tomstrails GPS UTM holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Tomstrails GPS UTM has 1.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 84% of Tomstrails GPS UTM's written reviews are positive against 100% of UTM Geo Map Y2Tech's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Tomstrails GPS UTM ships an update every 6 weeks, UTM Geo Map Y2Tech fortnightly. Both last shipped on October 24, 2026.
