User reviews

A wonderful free tool!

Lots of other apps charge a lot of money for what this board does for free. It’s so easy to connect my elderly father’s Bluetooth keyboard to the app and have it read what he types at anytime. I hooked it up to my HomePods so when he needs something and I’m in another room he can just type a message and it plays immediately for me everywhere in the house.

Easy to use

This is such a good idea, it’s so easy to use for all ages including my daughter and mom. I love that the verbal spelling functionality works out of the box but I can also customize the voice, the font, the keyboard.
