Cooee Mate app for iPhone and iPad

Cooee Mate is a location and communication app. Users create a friends list and when two friends are logged into the app they can share and track their movements using their phones’ GPS. The app also has a free text chat feature that connected friends can use.
You could use Cooee Mate to locate your mates at a music festival or other outdoor event.
The app can also be used to send an email containing your location to a large group of people that are not Cooee Mate users. This is ideal if you are trying to organise a meeting with people and you need to communicate your exact location in real time.
