SiteDocs does work when you do not have an internet connection. When you are offline, your signed documents are saved on your device until you connect to an internet source (WiFi, Cellular Data, etc.). Once you are connected, the App takes about 15-20 minutes to sync automatically, depending on the internet speed and your device settings.

However, if you need to send your documents through right away, you can do that by syncing manually; just follow these steps:

1. Select the "Sync" button on your Home Page.

2. Press the blue "Sync" Button under "Sync Data".

3. Wait for the Sync to finish.
