Designed for NoteBooks, is useful and amusing for driving a car, a camper, etc. - particularly if assisted by a 'navigator' travelling with you - when you have to cover long distances and want to regulate your speed in order to arrive at the planned time.MEDIAR calculates your speed average and, on its basis, predicts the time of your arrival. If the predictedtime is not right for you, MEDIAR is also able to calculate the average speed you should maintain in order to arrive at the desired time. The operation rules are very easy and intuitive.
