Ubitrek is designed to work with an IGNrando.fr account to sync selected content from the website to your Android device.
You can also use it without an IGNrando' account by importing your own GPX or KML files or for recording tracks and points.
Ubitrek can download maps along the tracks you have selected.
The downloaded maps are also available in other Ubicarta apps.
Ubicarta Plugins app gives access to subscriptions to the French topographic IGN maps.
You can choose between a monthly and a yearly subscription.
You can try the maps for free for one week by selecting either subscription.
