We are considering ways to allow users to upload their own files to Loftie via the Loftie app, but we can't guarantee yet that this function will be available.
In the meantime, you will be able to sync your content directly to Loftie through our integration with dozens of apps such as Spotify. In addition, you can build your own playlists on our app and play them later on your Loftie without needing a phone.
