Quickly and easily determine a remote GPS location from two, or more, geolocated points with compass bearings to that location. Specifically designed for use in the field, Field Triangulate supports: - Fully automated use of iOS device location. Compass bearings are best manually entered. - Manual entry/edit of any/all readings. - On map display in various display modes. - Manually update device bearings (e.g. for use with a compass.) - Share the triangulation to others. - Multiple latitude/longitude formats: -- Decimal degrees -- Degrees and decimal minutes -- Degrees, minutes and seconds. -- (Display for UTM.) Basic usage: Use your iOS device & compass to take bearing on a remote location from two locations and Field Triangulate will calculate and display the GPS coordinate for the remote location. Advanced usage: Enter readings provided from a remote person (perhaps by iPhone or radio) and add your own readings manually in order to calculate a remote location. ## Key features - Calculate remote GPS locations - Use compass bearings - Automated iOS device location - Manual reading entry - On-map display - Multiple latitude/longitude formats - Share triangulation results ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/field-triangulate/id548943416/reviews.md ### 4/5 — Ham Radio *2026-07-03* Several uses including SkyWarn storm spotting, Fox hunting and more. Will demonstrate at Ham club meeting. Would be even nicer if there was a way to easily automatically share among multiple spotter phones for multiple numbered or labeled targets during spotting events. APRS has something similar over radio, but not fully developed. Really wish this was available for Android. Thanks! ### 1/5 — I wish I had not wasted $7.99. *2024-03-08* I would like an app that does what this one is supposed to do. This one doesn’t do what it is supposed to do. This app is wildly inaccurate. I have been testing in Utah desert with large distinct landforms, similar to monument valley, that should be easy to point at and take a bearing. The accuracy is so far off the app is useless. Also, the layout and procedure is unintuitive and the documentation is poor. When you do figure out how it is supposed to work you also figure out how poorly the layout supports the function. Finally, the developer does not respond to email questions regarding functionality. This app would be a disappointment if it was free. It is a bad joke at $7.99. I think a refund should be provided but the App Store says this app is not eligible for a refund. ### 1/5 — Not intuitive *2023-10-29* Not easy to use intuitively. I tried to confirm the location of a peak using my location and couldn't see how to do it. ### 5/5 — Accurate! *2023-02-11* It'd as accurate as the accuracy of the compass bearings ### 1/5 — Just doesn’t work *2022-10-02, version 3.1.2* We have tried and tried but the app always puts a coordinates of -1 and will not read the internal campus. I know it’s not as accurate as a real compass but even the built in compass gives a number other than -1. ### 4/5 — Practice first *2020-11-27* Downloaded it last minute to use for fox hunting with my radio club as my son backed out last minute. I like it and have since practiced it and do like it as a one person operation. Can save points and historic readings. I recommended it to my radio club. ### 2/5 — Useful but problematic *2018-12-16* I’ve been seeing a consistent problem where projection lines disappear at carrying zoom levels, most often when close up. Another issue is when holding the phone sideways to sight down the edge of the phone the keyboard blocks the save button on screen. Additionally, being able to use the volume buttons would work well for locking the direction in. After setting a projection line the map at times will zoom out to a world view requiring panning and resetting the zoom level. Finally I’d like to be able to exit from creating a projection like without creating the line on the map. As it is now, tapping off to the side will return to the map but will still set a projection line at 0 degrees. One must then go to the listing of readings and delete it from there. **Developer response:** Hello Nick Thanks for the feedback. I didn't notice it here at first, but I see it now. Thanks for the concise reports. For next release I've fixed the second and fourth. The first is less in my control (the platform controls this) but I can investigate a workaround. The third is the app attempting to zoom to contain all the parts (readings, triangulation) but I'll look into it. Let me know if you'd like to be on the early access list to get a copy before next release. Thanks again for the detailed feedback. support@neukadye.com ### 4/5 — Good for radio fox hunting *2018-04-30* Attaching iPhone to rotating radio signal locator, this app helps to quickly triangulate on map where the “fox” is hidden. Note to developer the compass hdg should be more visible when setting up the fix. Maybe even using the camera as a target sight. ### 2/5 — Useless in Southern Hemisphere ? *2015-06-29* Disappointing. There would appear to be no way of changing the default north to South when entering coordinates in southern half of the planet. Emailed and fb messaged and received no reply. Shame because it would otherwise be ideal for my purposes of locating a distant stationary sound in dense forest. **Developer response:** I am sorry I failed to respond before. Your communications came in at a time I could not handle them, and then they slipped. I've added an issue tracker system since then. Have you checked out the new version (a complete rewrite) which should allow you to set south, and it save as the default (as a preference.) I'd appreciate your feedback on if the new application fits your needs. ### 1/5 — Very limited usefulness *2014-05-19* I thought I'd found an App that could be used in the field to spot-in multiple locations with heading to a feature to triangulate it's location....this is NOT it. Manual entry of coordinates. No map function. **Developer response:** I initially created this as a fully automated map based application, but soon found that one needed a manual compass to get sufficiently accurate readings, so hid certain aspects behind a settings screen. Please check out the new version, since this is a complete rewrite (given what I know today) with options (in settings) for you to enable the things you were missing. ## Frequently asked questions about Field Triangulate ### What is Field Triangulate? Field Triangulate is a productivity app that helps you determine a remote GPS location by using compass bearings from two or more geolocated points.
