I’m not seeing any research data on Andika either. It didn’t occur to me that anyone had done any on fonts other than the largest. (The listed features make sense for making letters distinguishable through multiple elements and preventing letter reversion). I also didn’t know OpenDyslexic existed, and should have done.
I have tried OpenDyslexic on my Kindle. I don’t particularly care for it. I generally use Bookerly enlarged.
In a windows environment ZoomText has many options available. A perpetual license is very expensive but an annual license is more affordable at $85 per year but only in the US. I have been using it since 2000 and find it very comfortable.
