DJ.Studio has an offline mode, meaning you can use the software without an active internet connection.
After installing and authorizing the application on the internet for the first time, you should be able to launch the app without a connection.
After you went off line, restart your DJ.Studio app and you will see this in the top right corner.
Note that any online features (Searching in Beatport, 1001Tracklists, etc.) will not be available in offline mode.
Test Offline Mode
You can follow these steps to test if offline mode is working:
Open DJ.Studio
Make sure you were signed in at least once.Disconnect your internet (turn the wifi off in your OS settings).
Restart the DJ.Studio app.
Check if DJ.Studio works still.
