SyFLUX: LED Marquee & Song ID
Scrolling Signs for Concerts
Free · Designed for iPad
Turn your iPhone or iPad into a full-screen LED sign. Scroll a message across the crowd, or tap Shazam to put the song that's playing up in lights.
SyFLUX turns your iPhone or iPad into a full-screen LED sign.
Type a message, pick a look, and hold it up. Your words scroll smoothly across the screen in glowing LED dots or crisp 8-bit pixels, big and bright enough to read from across the room.
Hear a song you love? Tap the Shazam button. SyFLUX identifies what's playing, puts it straight onto the marquee, and saves it to your song list for later.
LED MARQUEE
• Full-screen scrolling text with smooth, steady motion
• Two looks: LED, with round dots and a soft glow, or 8-Bit, with square arcade pixels
• Eight themes: Blossom, Ember, Forest, Midnight, Ocean, Paper, Rainbow and Sunset
• Crawl your message across the screen, or hold it still
• Adjustable speed, regular or bold lettering, and your choice of capitalization
• Keeps the screen awake while your message is up
SONG ID
• Identify songs playing nearby with Shazam
• Show a match as artist and title, title only, or artist only
• Keep a list of every song you've identified, with album artwork
• Tap a saved song to put it back on the marquee
• Open a song in Apple Music, or share it with friends
MESSAGES
• Save the messages you use most and bring one back with a tap
• Your messages and songs sync between your iPhone and iPad with iCloud
Made for concerts, games, airport pickups, parties and any moment you need to say something without shouting.
No ads. No accounts. Just your message, in lights.
