I updated the app about a week ago and I had to play with it the first time to get used to the new design, but seriously, its fine. Its slightly different, but that doesnt mean its awful. (However, I do not have any vision issues. So, I cant address that.) You do have to tap to get info that had been all on one page, but that doesnt bother me. A huge plus: you can actually look at the blog (the radar loops) without the app freezing or crashing.
