Hey! I'm a Marine flight student currently flying the TH-57, and I recently got a Samsung Galaxy Tab S2 8.0 to use as an electronic kneeboard. I have spent several hours toying around with about 7 different programs trying to find something suitable for me. iFly GPS is one of the best ones that I've tried. It has a slick, intuitive interface perfect for planning, flying, and shooting approaches with geo-referenced plates.
The one glaring problem, however, is the graphical resolution. My tablet has a resolution of 2048x1536, and this app looks like it was designed for something far lower and just blown up. I know that apps have to be scalable with different devices all with different capabilities and different resolutions, but compared to the other similar apps everything looks a little pixelated and blurry. Not just pictures, icons, and approach plates; even things that should be vectors, like the lines showing your flight route, and even text. It's not terrible, but it is definitely noticable.
I still think this is one of the best flying apps out there, but I am curious if you guys are planning on overhauling things to make it look cleaner and more crisp in some future release.
