User Reviews

"I love Thorium and have introduced it to my students for reading any digital content. It is doubly good when something that makes reading more accessible for visually impaired people is also something that makes things more flexible for all. It makes it so much easier to get buy-in for using it."

Suzanne Norman, Simon Fraser University, Canada

"I am very happy to have found this app. Its simple, easy to use, and most importantly, its very friendly for people who are blind and visually impaired."
