About Cardzilla
Type a message and it fills your screen in the biggest text that fits.
Cardzilla turns your phone into a card you can hold up.
Readable across a room, through a window, or in a noisy bar. Nothing to
set up, nothing to zoom.
MADE FOR
• Deaf and hard-of-hearing conversations
• People who don't use their voice, or can't right now
• Loud places where nobody can hear you
• Quiet places where you shouldn't speak
• Language barriers, where showing beats saying
HOW IT WORKS
• Type — the text resizes itself as you go
• Swipe to clear and start the next message
• Your note saves itself as you type, so it's still there when you come back
• Every message you clear is kept in History
• Star the notes you use often as favorites
• Shake to erase, if you want it
ALSO
• Light and dark mode support
• Available in 20 languages, matching your phone
