How can i transfer my sessions to my computer?

With your ONMiles, you have the option of transferring data to Geonaute Software or ONConnect (only compatible with Windows).
To do this, you need a special USB stick, previously sold in our stores: PC Connect (Ref: 8160540).
Then follow the instructions for transferring your sessions:


The readings displayed seem incorrect. how can i improve the accuracy of these readings?

To improve the accuracy of your data, we advise you to make the coefficient specific to your exercise. In fact, by basing your calculation on the number of strides taken over 400 m and the distance covered, you will be able to refine this coefficient which will give you more accurate readings
