Badge Magic

SailfishOS port of FOSSASIA's Badge Magic app for writing text to their LED badges that you get at FOSDEM and other open source parties. Write your text/statement/insult, choose animations and decorations, and write it to a badge in bluetooth listening mode. Save your favourites for later.

Doesn't support previews, emojis nor custom images yet.
