Yes! The Umapped Mobile App is accessible offline* so you don't have to worry about having a network connection while traveling. You can also add and edit notes, photos and videos while offline.
Please note, you must have a network connection for the original download of the trip therefore you must sign in before losing connectivity. Any new content will be synced automatically the next time you use the Mobile App with a network connection.
