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
