**** This app requires Special Playing Cards that can be purchased at https://www.qrspeak.com If you have recently lost your eyesight, have been blind since birth, or have limited vision, enjoying playing cards can be hard to do. 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. You can wear an earpiece so only you know what cards you hold. Cards that Talk also features a continuous scanner so that once the app is started there is no need to touch the device again until you are done enjoying playing cards. 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. Features - Continuous scanning; no tapping the screen after each card - variable speed control for voice - large start scanning button so no fumbling trying to find it Cards that Talk is free but will require our playing cards that can be purchased. Contact us at https://www.qrspeak.com and click the link to buy cards or we can answer any questions that you may have. 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.

ReceptionRating · Positive reviews · Number of ratings

Cards That Talk holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Cards That Talk has 7 ratings behind it against 1, so its average is the more settled of the two. 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.

UpkeepUpdate frequency

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.
