Thank you for your post. Unfortunately, at this time there is no way to synchronize map features automatically between devices, as any map features collected (tracks, points, etc.) are local to the app itself until such time as they are exported. In order to access your GPS tracks on your second device, you will need to export them from your first device and then import it into your second. This is a feature that we are looking into implementing in the future, but at this time it is still in the early research stages.
For more details on how to export and import features on an iOS device, please see the two help articles below:
In addition, please note that if you are using the app for work-related activities, you do require a Pro subscription for each device in use.
If you have any questions about this process please don’t hesitate to reach out to us via the form at support.avenzamaps.com
