At the bottom your current position is shown. To change the formatting of the gps coordinates see settings. To share your position long tap at the field, the device's share view will appear. Here you may also open your current position to Google Maps if installed.
At the bottom's right side the gps' accuracy in meters is shown. If the accuracy is less than 6.5 m it is probably insuffisant for nagivation and shown in read as a warning.
In case of bad gps accuracy the app tries to smooth the values for speed and heading to prevent from heavy jumping of the values.
