These are the Premium features unlocked by this license:
▪ Cloud backup and cross device sync of playback positions, playlist and episode states tied to your Google account
▪ Chromecast support
▪ Automatic download (e.g. when connected via Wi-FI)
▪ Chapter navigation in MP3 and M4A/AAC/MP4 files
▪ Sleep timer (stop playback at end of chapter, episode or after a specified time)
▪ Podcast specific settings (e.g. auto add to playlist, only keep x latest episodes)
▪ Up to two specific sync times per day

Please checkout the trial before you buy the license: You can test all Premium features for seven days in the free version. Simply start your trial period in Settings > License.

Install this in addition to the free version of uPod as this license app alone doesn't do anything.
