Description
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
Recent changes: • Now available in 20 languages. • Your note saves as you type, so it survives if the app closes. • Fixed letters being dropped while typing, especially when typing fast or using voice input. • The back button and back gesture now work normally. • The app now follows your device's rotation lock.

Works great for communicating with my deaf friend, I used to use Samsung notes, but I like that the text on this is bigger, and it's nice to be able to delete all the text at once by just swiping left on the screen (or hitting the trash can).

I want to give you 5 stars, but I'm unable to rotate the app screen!! Awesome app tho, fix the Auto Rotate I'll bump it to 5 star. I use it to share my phone screen to my TV to communicate with my grandpa who can't hear well.

This app has no saved note clips feature or history feature. The Cardzilla app on iPhone has the useful features like saved note clips and history notes. You must add the features to this app (Android version) now. I need these so much for saving my time.

Currently using this to communicate with a coworker, but I need the shake to erase and other functions to exist for android, not just iPhone 🙃
