I probably need to go to my optician and update my contact lenses and glasses anyway, but with the introduction of Zwift on iOS (which I on the whole think is a great experience!) some of the fonts - the rider list on the right for instance - are a bit hard to read. I use an iPad Air 2 with a Tacx handlebar bracket.
It would be nice if I could do some font size adjustments (and color perhaps?) in the user GUI. Please put this in future updates
