Our present goal is to make all future apps equally readable from the smallest mobile smart phone to the largest tablet. But that makes development exponentially more complicated as you then have to program for multiple screen sizes.
Team OnCell did an amazing job of enabling our images to grow in proportion to the width of each screen. But none of us imagined how that would affect the height of the image with each larger screen size. During our alpha test of 14 June 2016, which included 11 people and 12 devices, we found that as the screen sizes grew larger, the vertical images grow longer and thus fell further and further “below the fold.”
This means, quite simply, that beyond the iPhone 5, you could not see an entire vertical image on the screen, as in the image above taken on an iPhone 6. The team and I feel very strongly that you should.
