Your library already lives on your server. JF-1 is the pocket-sized way to take it with you.
Pick up. Tune in.
One thumb on the wheel and your library starts to move. The display shows the cover and nothing else, and every key does exactly what its icon says. No screen to unlock and no app to open, so the song is playing before the moment has passed.
Touch wheel
Scroll, skip and select

Pixel display
The cover and a progress bar,
nothing more
Press play.
Your whole Jellyfin library in a player that does one thing. No feed and no algorithm deciding what comes next. Just your music, wherever the SIM card finds a signal.
JF-1 ยท Your library, one album at a time
