The iPhone is nothing like any other phone that I have seen in direct sun light. The mini pad 4 was not as bright but I only tried once. I wanted a larger screen due to on the verg of having to wear glasses. I think I may try an extra extension to bring the iPhone closer to me. I also was thinking about making a sun screen for the mini pad but have not yet. I'm also using bad elf with my iPhone and I had a connect problem with the mini so that is another reason I have not pursued more. But I plan too.

iPhone use to not be sun light readable and I amagine they will continue to improve faster than any other off the shelf glider display.

Why the Bad Elf with the iPhone? Both my 5s and my 6 Plus work fine from the built in GPS. In fact the 6 Plus, with its built in barometrics, makes quite a decent stand alone glide computer. Better still if you connect it up to your variometer, but very good all by itself.
