Ask HN: Online Learning for Dyslexic Kids?

What are the good online learning programs, specifically designed for dyslexic kids?

I am looking for a program where a child (K-5 elementary) could learn on her own, without much of an adult guidance. I found two great online resources to learn math (Matific and Beast Academy - works great), but I could not find any comparable resources to learn English for dyslexic kids.

What are the best resources for dyslexic kids at the elementary school level?
