HUDWAY APPS / WIDGETS
HUDWAY has several apps available for the Glass (you can use other third party apps as well) including a GPS app, speedometer app and the glass apps (although you will need to install each of these apps they can all be launched from within the Widgets app).
The GPS navigation projects the road you need to follow (can also work offline with just your GPS enabled) while the glass app has 4 different speedometers some of which are reminiscent of very old cars (there are also two more speedometers with regular red/green numbers).
Moving to the trip information widget from here you can check the maximum and average gas consumption, advices you of your current eco "level" based on your speed and acceleration, records the miles per gallon/cost and finally it also has a compass.
With the speedometer app you can always know if you're within the speed limit or not since when you’re not it turns red (it automatically downloads speed limits in the country you're in the first time it's used).
The land meter (also part of the glass app) up may not be of any use to me but it should be for people with odd road vehicles who like using them any chance they get.
Final screen shows a large watch, a small compass right beneath it and the current temperature (or was it humidity level?).
