There is the option of braille cards but they are bulky to shuffle and if recently vison impaired you need to learn how to read the braille on the cards. We have created a new way of playing cards for the blind or vison impaired called Cards that Talk. You simply place the card under the camera on the apple device and it will read the card to you.

There are buttons that you can either slow down the speed of the voice or speed it up depending on your preference. All that is left for you to do is enjoy playing cards again.

The cards are professionally printed and will hold up like any other deck of cards. Since there is no braille on them they are smooth. This makes them easier to shuffle and to play with.

Cards That Talk holds the better App Store score, 4.3 against 4.0.

Written reviews complicate that: 100% of ExplosionMotor's written reviews are positive against 50% of Cards That Talk's, so the app with the better star average is not the one people write more warmly about.
ExplosionMotor ships an update every 40 months, Cards That Talk every 3 months. The most recent releases landed on August 10, 2026 and September 13, 2026 respectively.
