Portable gadgets: Share your location
You need it because:
Sending your location to a client needs to be as accurate as possible. Too many GPS systems provide an approximate location and place little emphasis on an exact address or specific point on a large development site.
The nitty gritty:
This app has divided the whole planet into a grid made up of 3m x 3m blocks. Each one has a permanent but randomly assigned combination of three words to demarcate its location. These words are shared via the app to provide the most accurate positional reading possible.
The app is already being used extensively in more than 170 countries. It’s simple to use anywhere in the world without having to download any extra maps or extensions to GPS systems.
Free; Google Play and iTunes
