iGeoTrans is a perfect solution to replacing dedicated handheld GPS navigation devices for iPhone, iPad and iPod touch users. It supports surveying, mapping, fieldwork and related fields for any area in the world.
- Locates user's location with high accuracy.
- Allows users to manage and load waypoints, displaying straight route from user's location to the selected waypoint on the map in real time.
- Allows users to compute the area or distance directly on the map
- Displays direction, digital compass, route and the straight-line distance between user's location and the selected waypoint on the map in real time.
- Users can manage the reference coordinate systems by adding, removing, and updating them.
- Geodetic data in a reference coordinate system can be transformed to those in another with high accuracy (there are 7 parameters for datum transformations between a user-defined coordinate system and WGS 84 Global definition and vice versa or among the user-defined coordinate systems).
- Converts geodetic coordinates to map grid coordinates and vice versa using one of 26 different map projections for any area in the world.
- Easily imports or exports waypoint coordinates in different coordinate systems and input formats.

Ratings and Reviews

Only good for two points and not accurate

The App only allows two points, then sends you to purchase the full App ($50), if you want to plot a 3rd point. I bought the full App because I needed a 3rd point to complete a measurement.

However, if you’re looking for accuracy within around 5 feet, this App won’t work for you. GPS is known to only be accurate within several feet using handheld phone devices, and it cost me the price of the App to figure that out. Here’s my review from the full App:
“Because the App relies on GPS signal, it is impossible to get a steady and accurate fix within a 5-8 foot circle using a handheld phone device. The GPS reading cannot get down to inches or within 5 feet and the signal constantly shifts within this range. Each time I take a reading (using the latest iPhone X with cellular and WiFi), I get different outcomes. It seems generally correct, if you don’t mind being off by several feet. But for surveying purposes, it is not useful, accurate, consistent or reliable. If you’re looking for measurements within inches or a couple feet, this App is a very expensive novelty that will have you frustrated walking in circles with no useful result.”

Great app for surveyor


I used to find or mark location using handle gps but sometime I need to use smartphone. I try many app but finally i find out this. Very useful app from Vietnam :) 5* for this app.

Does what I wanted it to


I was looking for an app that produces quick, precise lat & long. No useless extras pointing out coffee shops; just decimal coords. This one seems to nail it -- and you can't beat the price with a stick.
