Coordinator-Collect Coordinate v7.9.1

Using Coordinator app, you can collect coordinate data from land on whatever coordinate system you want, choosing from defined systems. You can collect GPS coordinates. You can use the app as a GPS tracker. You can view a coordinate data on the map and also search by address and see that on the map. You can get directions to that point. You can search by longitude/latitude. You can convert an existing coordinate into another coordinate system. You can do this by typing coordinates manually or opening an XLSX file which contains coordinates. You can display circumference and area measurements of some coordinates by opening the file which created before. Also you can measure distance and area for some coordinates which determined manually on the map. You can display a KML file on the map. There is also a compass tool. Coordinator app contains several useful tools for people interested in coordinates, maps and geographic information systems (GIS).
All of the features above are free.
On the other hand if you become a Coordinator Pro subscriber, you can benefit from many extra features in addition to these features. With Coordinator Pro, subscribers can use some extra features such as 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, making elevation & address querying and so on. It is ad-free.
Besides longitude/latitude, subscribers can find out the altitude value of a point on the map. You can search by address and so that locate it on the map and learn the GPS coordinate (longitude/latitude or northing/easting) value of this place. The address locating feature works based on maps services and it's very effective.
If you are a subscriber, you can use the Coordinator Web app. So that you can use the cloud database features of the Coordinator app on the web page on your computer 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 the data movements made in the mobile app in the field, in the web browser on your computer.
