@Tusky Personally I find OpenDyslexic much more readable than traditional fonts, but I've not been diagnosed with dyslexia yet.

What I've seen so far is that dyslexia fonts can be hit or miss because there are several types of dyslexia in different degrees (it's not limited to those famous reading issues that everyone hears about).

I'd push for having OpenDyslexic available in every app if I could.

From experience I can tell that the Alta variant works better in user interfaces, IIRC it uses less vertical space. But that's something worth testing in the app itself.

I've heard of Atkinson Hyperlegible elsewhere, I didn't really feel any difference but it might be quite approachable since it's much closer to traditional fonts.
