ARTIST KNOCK
Your bias’s news, mood and all
New messages arrive with expression, light, a chime and vibration.
Then press the button to hear the voice message.
Example message
A sample chime will play. Vibration is shown as device movement, and no artist voice is played.“We won first place today! Thank you so much!”

Pick a knock to try.
Four senses together
Expression, light, sound and vibration. Turn on only the ones you want.
A rhythm for each message
Knock patterns that match each type of message and news.
Knocks that carry a mood
Expressions that change with the mood the artist chooses.
