The GPS logger field is quite crowded, but I don’t think I have come across one yet with such a stylish user interface. Designed for today’s touch-centered devices, the application also has practicality at heart.
The software is designed to record a GPS track which can be uploaded and viewed in Google Earth. Uniquely it is designed to save battery life by switching the power-hungry GPS receiver on and off at specified intervals, therefore allowing extended use while for example hiking.
